The NRI e-Workshop series
4:00 pm, Harvard University, Pierce Hall room 209
The series is aimed at educating both our industry sponsors and other university participants (both students and PIs) on specific research topics being done at NRI centers. You are invited to participate the Quantum Transport Studies of Strongly Correlated Electrons for Next Generation Logic Devices e-Workshop, to be presented by Matthew Gilbert, UT Austin & John Shumway, Arizona State on February 27, 2007, 4:00-5:30p eastern / 3:00-4:30p central / 2:00-3:30p mountain / 1:00-2:30p pacific. This e-Workshop is presented via Microsoft Live Meeting and a phone bridge.
We have a limited number of simultaneous connections available; therefore, we ask each company to select a site coordinator and reserve a conference room with a projector to accommodate multiple participants. To participate, all you need is a PC with internet connection and a phone line. Multiple sites may participate from each company.
To participate in this e-Workshop, please register on-line at http://www.src.org/nri/eworkshops.asp
Site coordinators will be e-mailed with the detailed log-in information approximately one week prior to e-Workshop. Immediately following the workshop, site coordinators will be asked to provide a rating, feedback/comments on the workshop, and the number of participants from that site via an on-line survey. This survey should take approx. five minutes and greatly assists us in making our e-Workshops better.
Abstract: As semiconductor devices are scaled further down to increasingly smaller sizes, the number of electrons participating in the transport continues to shrink as well. The combination of reduced dimensionality and number of electrons forces the electrons to participate in a well choreographed dance as they respond to applied fields. Devices which operate in the regime of strongly correlated electron states are predicted to exhibit exotic and dramatic changes in the resultant output characteristics. Currently, one of the most popular vehicles for observing and exploiting these effects are semiconductor quantum wires. This is due to both academic and industrial interest in the growth, characterization, and implementation of quantum wires as a possible means of extending the lifetime of CMOS. Furthermore, with appropriate gating, we may vary the electron density inside the quantum wire over several orders of magnitude easily reaching the regime where strong correlations occur. As a corollary, there is also a great need to find reliable modeling tools to characterize and benchmark the physics inherent in these new devices prior to fabrication. In this talk, we will discuss the use of path integral Monte Carlo to determine the transport properties of low density gated semiconductor quantum wires. This path integral method is well suited for high-accuracy treatment of electron correlation, finite temperature effects, and non-fermi liquid behavior, such as spin-charge separation. In addition, the path integral method can also be used to calculate experimentally relevant quantities such as conductance. The goal of these calculations is to investigate structures that would use spin-charge separation as an electrical means of generating spin waves and currents for low-dissipation logic devices.
If you have any questions, please let me know. We look forward to your participation.

SRC e-Workshop Graphene

Abstract: Our research project is aimed at developing a new 2 dimensional carbon-based electronic material for low dissipation high-speed nanoelectronics. The idea is based on the exceptional electronic transport properties amply demonstrated in carbon nanotubes nanotube-based transistors such as the non dissipative transport observed up to room temperature. We grow ultrathin graphite epitaxially on single crystal silicon carbide. The system composed of a few graphene (one atom-thick graphite layer) layers. The interface graphene layer is electron doped due to the built-in electric field between grapheme SiC, and the other layers are essentially undoped. We show that unlike graphite the charge carriers show Dirac particle properties (i.e. the electronic band structure is described by the Dirac-Weyl equation rather than the normal quadratic dispersion relation). This property shared with many 2d graphitic structures is at the origin of ballistic properties of carbon nanotubes. More precisely, we observe an anomalous Berry's phase, weak anti-localization and square root magnetic field dependence of Landau level energies. Epitaxial graphene shows quasi-ballistic transport and long electronic coherence lengths; properties which may persists above cryogenic temperatures. Epitaxial graphene can patterned using standard lithography methods and characterized using a wide array techniques. These favorable features indicate that interconnected room temperature ballistic devices may be feasible for low dissipation high-speed nanoelectronics.
If you have any questions, please let me know. We look forward to your participation.

NRI e-workshop: Graphene: A New 2-Dimensional System for Electronic Applications presented by Philip Kim of Columbia University
Abstract: The massless Dirac particles moving at the speed of light has been a fascinating subject in relativistic quantum physics. Graphene, an isolated single atomic layer of graphite, now provides us an opportunity to investigate such exotic effect in low-energy condensed matter systems. The unique electronic band structure of graphene lattice provides a linear dispersion relation where the Fermi velocity replaces the role of the speed of light in usual Dirac Fermion spectrum. We will discuss the unusual electric transport properties discovered in this novel 2-dimensional system, such as unusual quantum Hall effect and minimum conductivity that manifest quantum mechanical effects even at room temperature. Employing enhanced quantum phenomena in combine with nanofabrication, novel electronic and spintronic device applications based on electric and magnetic field effect discovered in graphene will be discussed.

NRI e-workshop: Ballistic Spin Transport and Injection
Presented by Vincent LaBella of the University at Albany
Abstract: Harnessing the spin as well as the charge of the electron holds great potential to produce novel multifunctional device structures that may help in overcoming the impending roadblocks facing CMOS technology. One of the trusts of the INDEX center is to investigate quantum dot based spintronic devices, which have several advantages over larger scale spin devices such as the spin-FET in part due to their smaller size. Crucial to these and all spintronics devices is spin injection and detection. This talk will discuss these quantum dot based devices and the various contact methods for spin injection and detection. A special focus will be on ballistic or tunnel injection, which holds the greatest potential for spin injection. In addition, results from a spin polarized ballistic electron emission microscopy experiment will be presented that can measure spin dependant scattering in ferromagnetic metal-semiconductor Schottky contacts. These contacts have potential to be utilized as spin injectors.

Abstract: Spintronics devices made of magnetic multilayers, such as giant magnetoresistance (GMR) and related tunneling magnetoresistance (TMR) devices, have been turned into commercial products at record speed. Although the applications of these devices have primarily been in the areas of magnetic field sensors and magnetic memory elements, the recent breakthrough in a new class of devices, termed spin-torque devices (STDs), has demonstrated new functionalities for these all-metal, room-temperature devices. For traditional magnetoresistive devices, the relative orientation of the magnetization of different layers, which determines the device characteristics, is controlled by an Oersted magnetic field. In contrast, the magnetizations in a STD are modulated by a spin-polarized electric current via spin torque transfer. It has been demonstrated experimentally that the device state can be switched by a tiny DC current in the sub-nano-second time scale. Furthermore, the passage of a DC current through a STD can generate steady, phase-coherent microwave signals. In this talk I will review the recent progress in this area and the latest research in STDs within the Western Institute of Nanoelectronics. I will also discuss potential applications of STDs for high-speed, low-dissipation logic and high-frequency signal processing.

A Wrinkle in Space: Quantum Isospectral Nanostructures
4:00 pm, Harvard University, 29 Oxford st, Pierce Hall room 209
Abstract: At the juncture of geometry and wave mechanics lurks a subtle yet far-reaching spectral ambiguity. There exist drum-like manifolds that resonate at identical frequencies but possess different shapes, making it impossible to invert a measured spectrum of excitations into a unique physical reality. An ongoing mathematical quest has recently compacted this conundrum from higher dimensions to planar geometries. Inspired by these isospectral domains, we introduce a class of quantum nanostructures characterized by matching electronic structure but divergent physical structure. We perform quantum measurements (scanning tunneling spectroscopy) on these “quantum drums” (degenerate two-dimensional electrons confined by individually positioned molecules) to reveal that isospectrality provides an extra topological degree of freedom enabling the reconstruction of complete electron wavefunctions—including internal quantum phase information—from measured single-eigenmode probability densities. These methods are general and extensible to other nanostructures and fabrication techniques.
In these experiments we utilize the exciting technology of atomic and molecular manipulation: a custom-built scanning tunneling microscope, operating at low temperature in ultrahigh vacuum, is used to assemble nanostructures atom-by-atom to generate versatile quantum laboratories at the spatial limit of condensed matter.

3rd Annual Cornell Nanoscale Facility Fall Workshop - Defining the Interface between Nanoscience and Geology
Cornell University, Ithaca, NY
** Funding available for graduate or post-doctoral researchers to attend **
Overview: While nanoscale research and geology at first glance deal with vastly different time and length scales, several areas exist where nanoscale research has profound impact on geologic questions. Density functional approaches provide crucial tools for predicting high pressure crystals beneath the Earth's crust. Fluid transport through porous rock can benefit from tools used in microfluidics. While biomineralization creates macroscale structures like shells and coral, the nanoscale process that proteins use to create large inorganic structures is an active area of research.
Format: This workshop will highlight issues at the interface between nanoscience and geology. It will also demonstrate nanoscale computational tools that can propel the next generation of geology researchers. The morning sessions will consist of lectures from leaders in the field who will discuss current issues and approaches available. Afternoon sessions will provide hands-on sessions where participants will get to work directly with these codes. In some cases, participants will learn directly from the code's creator.

3pm eastern / 2pm central / 1pm mountain / 12 noon pacific.
This e-Workshop is presented via Microsoft Live Meeting and a phone bridge.
We have a limited number of simultaneous connections available; therefore, we ask each company to select a site coordinator and reserve a conference room with a projector to accommodate multiple participants. To participate, all you need is a PC with internet connection and a phone line. Multiple sites may participate from each company.
Site coordinators will be e-mailed with the detailed log-in information a few days prior to e-Workshop. Immediately following the workshop, site coordinators will be asked to provide a rating, feedback/comments on the workshop, and the number of participants from that site via an on-line survey. This survey should take approx. five minutes and greatly assists us in making our e-Workshops better.
Abstract: Complex perovskite oxides exhibit a rich spectrum of functional responses, including magnetism, ferroelectricity, highly correlated electron behavior, superconductivity, etc. The basic materials physics of such materials provide the ideal playground for interdisciplinary scientific exploration. Over the past decade we have been exploring the science of such materials (for example, colossal magnetoresistance, ferroelectricity, etc.) in thin film form by creating epitaxial heterostructures and nanostructures. Among the large number of materials systems, there exists a small set of materials which exhibit multiple order parameters; these are known as multiferroics. Using our work in the field of ferroelectric(FE) and ferromagnetic oxides as the background, we are now exploring such materials, as epitaxial thin films as well as nanostructures. Specifically, we are studying the role of thin film growth, heteroepitaxy and processing on the basic properties as well as magnitude of the coupling between the order parameters. In our work we are exploring the switchability of the antiferromagnetic order using this coupling.
What is the importance of this work? Antiferromagnets(AFM) are pervasive in the recording industry. They are used as exchange biasing layers in MTJ's etc. However, to date there has been no antiferomagnet that is electrically tunable. We believe that the multiferroic BiFeO3 is one compound where this can be observed. If this is proven, the next step is to explore the coupling of a ferromagnet to this antiferromagnet through the exchange biasing concept. Ultimately, this will give us the opportunity to switch the magnetic state in a ferromagent( and therefore the spin polarization direction) by simply applying an electric field to the underlying antiferromagnetic ferroelectric. In this talk, I will describe our progress to date on this exciting possibility. We are currently focusing on understanding the coupling between AFM and FE using a combination of scanning force microscopy and photoemission spectromicroscopy.

Colloquium: "There’s Plenty of Room in the Middle: A View from the Bottom"
Morris Loeb Lectures in Physcis Don Eigler IBM Almeden Research Center
4:15 p.m. Harvard University, Jefferson 250
Tea in Jefferson 450 at 3:30 p.m.
In 1959 Richard Feynman gave a remarkably prescient and now-famous talk titled "There's Plenty of Room at the Bottom" in which he spoke of the possibilities afforded by extreme miniaturization. In that talk he discussed a "great future" in which "we can arrange the atoms the way we want." Feynman's "great future" arrived in 1989 with the discovery of ways to use Low Temperature Scanning Tunneling Microscopes (LT-STMs) to manipulate individual atoms and construct atomically-precise structures. In this first of three Loeb Lectures, I will briefly review the essentials of tunneling microscopy and atom manipulation, highlighting examples of how we use atom manipulation as a means to get at the physics of nanometer-scale structures and to explore novel ways of exploiting quantum mechanics to achieve the goals of classical computation. Time permitting, I will reflect upon the challenges we face in building ever larger structures and the extraordinary opportunities for science and technology that would come from the routine ability to assemble quantum-functional nanometer-scale 3D structures of our own design: the middle.
LECTURE I
3:00 p.m. Harvard University, Jefferson 250
"Computation in Nanometer-Scale Structures: Molecule Cascades"
In this second Loeb Lecture I will discuss a new class of nanometer-scale structures called "molecule cascades," and show how they may be used to implement a general-purpose binary-logic computer in which all of the circuitry is at the nanometer length scale.
LECTURE II
3:00 p.m. Harvard University, Jefferson 250
"Classical Computation in Quantum Nanostructures: A Long Road to an Uncertain Future"
In this third Loeb Lecture I will discuss how we have used the scanning tunneling microscope to measure the spin-excitation spectra of individual atoms. Utilizing spin-excitation spectroscopy as our primary tool, we are now capable of extracting exchange coupling energies, anisotropy energies, and information on the spin configuration of nanometer-scale structures. What we learn from these experiments will hopefully allow us to engineer the “energy landscape” of a system of spins in order to achieve nanometer-scale binary logic circuits that operate using only the spin degree of freedom.

Educational Programs Holiday Lecture: Squishy, Gooey, Stretchy: The Science of Making Pizza
Join us at the 2007 Harvard Holiday Science Lecture as we observe, touch, taste, and explore some of your favorite foods. Kids, families, students, teachers and the curious are welcome! You'll discover the physics, chemistry and biology of cheese and bread, look at them under a microscope, taste the cheese we make (yum!), and learn about digestion (yuck!). Using live experiments and interactive demonstrations with children from the audience, we will investigate the wonders of pizza. Come and be a scientist with us! This interactive presentation, given by Amy Rowat, Daniel Rosenberg and Howard Stone, is based on a famous set of lectures first given to children a century ago by the great scientist Michael Faraday.
