NRI e-Workshop: Bilayer pseudoSpin Field Effect Transistor (BiSFET): device concept and logic implementation
to be presented by Professor Leonard Frank Register of The University of Texas at Austin
Abstract: I will present a new type of graphene-based transistor intended to allow lower voltage, lower power operation than possible with Complementary Metal Oxide Semiconductor Field-Effect Transistors, a Bilayer pseudoSpin Field Effect Transistor (BiSFET).
I will begin with a background presentation of the underlying physics of possible phase-coherent many-body exotonic interlayer tunneling effects above room temperature. I will then describe the basic structural elements of a BiSFET and the predicted current-voltage characteristics. As will be shown, BiSFETs are not drop-in replacements for MOSFETs. Thus, any BiSFET-based logic must also vary significantly from CMOS. Therefore, a functional BiSFET device model was developed and used in SPICE?-based circuit simulations to help develop and test BiSFET-based logic elements. I will describe the resulting layout and simulated operation of a BiSFET-based inverter and a programmable NAND/OR gate. Notably, for simulated inverter switching (with a fan-in and fan-out of four) the average energy consumed per clock cycle per BiSFET was on the order of 0.01 aJ at 100 GHz. For comparison, current MOSFETs consume ~100 aJ per switching on average at an approximately 5 GHz clock frequency, and 2020 "end of the roadmap" CMOS will still consume about 5 aJ per switching [based on information from the ITRS Roadmap]. However, these estimates are rough and do not consider the parasitic power losses of delivering the clock signal to each BiSFET as required for the proposed BiSFET-based logic.
However, while theory indicates that the invoked phase-coherent many-body excitonic tunneling effect in graphene bilayers may survive at room temperature unlike in other condensed matter systems, we recognize the uncertainties of theoretical predictions. Equally relevant is the ability to scale the device down to such small sizes without destroying or severely degrading the condensate properties. The device fabrication would impose numerous challenges as well. Thus, this work should be viewed merely as an initial proposal of a new type of transistor, which will hopefully stimulate further experimental and theoretical work.

NRI e-Workshop: On the Possibility of an Electronic-structure Modulation Transistor
to be presented by Hassan Raza and Edwin C. Kan of Cornell University
Abstract: We have recently invented an electronic-structure modulation transistor (EMT), which can possibly be used for post-CMOS logic applications. The device principle is based on the bandwidth modulation of a midgap or near-midgap localized state in the channel by an external gate voltage. Theoretical analysis of the functionality of the EMT would be presented using a single-band tight-binding method coupled with the non-equilibrium Green's function formalism for quantum transport. Our objective is to confirm if an EMT has a self gain and if it can overcome the 2.3kT/decade thermal limit with low supply voltage. ON current depends on the bandwidth of the state and limited by the quantum of conductance for a single band. OFF current is set by the gate leakage and tunneling through higher bands, which is expected to be small if these bands are few eV above the localized state energy level. Possible device implementations in molecules and graphene nanostructures would be discussed.
Preliminary experimental efforts geared towards the proposed mechanism, although still not a working prototype, would also be presented in a double-gated structure using a 20 nm long and 10 É m wide channel consisting of Au nanocrystals (NCs) and nitride traps. Putting negative charge on the NCs is expected to result in wavefunction extension over larger distances due to lifting of the energy levels resulting in reduction in the effective barrier. In transfer characteristics, a non-linear increase of the drain current on the top gate voltage and the charge stored in the channel is observed, which is attributed to the stronger coupling between Au NCs due to the electronic-structure modulation of the Au NCs / nitride composite.

NRI e-Workshop Yves Acremann of Stanford University
will speak on: Magnetization Manipulations by Spin Transfer: Gain in Magnetism
Abstract: The magnetization of a ferromagnet can be manipulated by injection of a spin current. Surprisingly the injected spin current does not act like a magnetic field, but modifies the ferromagnetic damping. Under certain conditions the damping can be reversed entirely, leading to persistence oscillations of the magnetization. This talk will focus on nanostructure dynamics in spin torque devices.

NRI e-Workshop: From NEMO1D and NEMO3D to OMEN: moving towards atomistic 3D quantum transport in nano-scale semiconductors
to be presented by Gerhard Klimeck of Purdue University
4:00 pm ET
Abstract: Lessons learned in 15 years of NEMO development starting from quantitative and predictive resonant tunneling diode (RTD) to multi-million atom electronic structure modeling and the path for OMEN are laid out. The recent OMEN capabilities enable realistically large 3D atomistic nano-scale device simulation. The end of Moore's Law has been falsely predicted many times. Irrespective of "details" of continued scaling in heat dissipation, lithography, materials, or financial viability, the fundamental limit of transistors containing an indivisible, countable number of atoms is coming closer. In this regime the detailed atom arrangements and quantum mechanical behavior of the carriers are critical in the understanding of the device. Not only are the structures getting smaller, but they are morphing from planar to 3-D topologies and new atom species are introduced. From now on the distinction between new device and new material is blurred and transport modeling must embrace atomistic and quantum concepts.

NRI e-Workshop: Suman Datta of Penn State University will speak on Tunnel Transistor Architecture and its Viability for Energy Efficient Logic Applications
Abstract: Since 1926 it is well accepted that the continuous nonzero nature of solutions to Schrodinger's wave equation used to represent electrons, even in classically forbidden regions of negative kinetic energy, allows for a finite and tunable probability of tunneling from one classically allowed region to another (for example band to band tunneling in a semiconductor). We have recently initiated the investigation of a novel transistor architecture based on such tunneling mechanism as a step towards exploring steep switching transistors for energy efficient logic applications. In this seminar, I will attempt to address the following topics regarding the tunnel transistor architecture: a) the choice of appropriate materials to tune the transfer characteristics over a specified gate swing b) the characteristic screening lengths to observe saturation in the output characteristics of the device needed to provide gain c) an effective way to estimate the switching speed of such devices and d) the importance (if any) of nonequilibrium carrier dynamics on the device terminal characteristics.

NRI e-Workshop: Organic Exciplex Transistors
Presented by Marc Baldo of Massachusetts Institute of Technology
4pm ET / 3pm CT / 2pm MT / 1pm PT
Abstract: Excitons, bound pairs of electrons and holes, mediate the interconversion of charges and photons and thus can be used for an efficient interconnect between electronic circuits and optical communication. The ability to guide excitons in space can lead to an excitonic switch that routes an optical signal without converting them to electrons. Recently, High et al. demonstrated the excitonic transistor using indirect excitons formed in AlGaAs/GaAs coupled quantum wells at the temperature of 1.4K [1]. Organic semiconductors are a suitable media to manipulate excitons because excitons in organic molecules are stable and long lived at room temperature. Using spin-disallowed transition, excitons can last up to milliseconds. This is more than sufficient to enable exciton propagation over large distances and the operation of excitonic circuits.
In this work we aim to demonstrate an exciton transistor based on organic semiconductors that can operate at room temperature. Exciplexes, indirect electron-hole pairs situated on adjacent molecules, are interesting because they are spatially oriented with certain e-h spacing. We can guide exciplexes using the energy gradient controlled by external electric fields. We show that by changing the voltage bias over a 4,4',4''-tris-(3-methylphenylphenylamino)triphenylamine (m-MTDATA)/bathocuproine (BCP) heterojunction the energy of the exciplexes can be changed over 40meV, well above thermal energy at room temperature. We also observe that long-lived exciplexes can be created with a lifetime of several microseconds at room temperature in the phosphorescent system of N,N'-diphenyl-N,N'-bis(3-methyl-phenyl)-l,l'biphenyl-4,4'diamine (TPD)/ iridium(III) bis(4,6-difluorophenylpyridinato-N,C2')picolinate (Firpic). These results open a promising route toward the spatial manipulation of exciplexes in organic semiconductors.

Ultra-fast metal-Insulator transitions in oxide semiconductors as a paradigm for electronic switches to be presented by Shriram Ramanathan of Harvard University
4pm ET / 3pm CT / 2pm MT / 1pm PT
Abstract: Electronically triggered sub-picosecond metal-insulator transitions in oxide thin films could enable novel electronics for logic and memory technologies, simultaneously offering unique opportunities that may not be possible with conventional semiconductor FETs. We will describe on-going efforts in our laboratory on the problem of gated phase transitions in oxide semiconductors, particularly vanadium oxide thin films. Although a material of interest for several decades since Morin’s report in 1959, a number of questions need to be addressed critically, that relate to un-ambiguous demonstration of electronic triggering of the phase transition, structural stability and lattice distortions, as well as fundamental transport properties in nanoscale devices. Overall, this makes an exciting research problem in materials physics, at the same time, connecting naturally with the NRI objectives.

BASF Advanced Research Initiative presents: Dr. Raymond M. David: The Value of Characterization for Nanotoxicology
Abstract: Nanotechnology is a rapidly emerging field of great interest and promise. As new materials are developed and commercialized, hazard information also needs to be generated to reassure regulators, workers, and consumers that these materials can be used safely.
The biological properties of nanomaterials are closely tied to the physical characteristics including size, shape, dissolution rate, agglomeration state, and surface chemistry, to name a few. Furthermore, these properties can be altered by the medium used to suspend or disperse these water-insoluble particles.
However, the current toxicology literature lacks much of the characterization information that allows toxicologists and regulators to develop ‘rules of thumb’ that could be used to assess potential hazards. To effectively develop these rules, toxicologists need to know the characteristics of the particle that interacts with the biological system.
Lack of characterization could also lead to different laboratories reporting discordant results on seemingly the same test material because of subtle differences in the particle or differences in the dispersion medium used that resulted in altered properties and toxicity of the particle . For these reasons, good characterization using a minimal characterization data set should accompany and be required of all scientific publications on nanomaterials.
Dr. Raymond David is Manager of Toxicology for Industrial Chemicals in the BASF Corporation. He received his Ph.D. in Pharmacology from the University of Louisville, after which he was a Postdoctoral Fellow at the Chemical Institute of Toxicology in Research Triangle Park. Prior to his position at BASF, Dr. David worked at Microbiological Associates and Eastman Kodak. He has experience conducting inhalation, pulmonary, reproductive, and systemic toxicity studies.

For example, the quantization of the electron motion around the circumference of a tube gives rise to electron-hole symmetric subbands analogous to particle/antiparticle pairs. Here we present new results on nanotubes in the spirit of this analogy, including the observation of topological spin-orbit coupling due to the nanotube’s curled up dimension, and measurements of ultra-efficient electron-hole pair production by high energy carriers.

Center for Excitonics Seminar Series: Self Assembly for Nanostructured Electronic Devices Presented
by Dr. Charles T. Black, Center for Functional Nanomaterials
Brookhaven National Laboratory
Abstract: The Center for Functional Nanomaterials (CFN) at Brookhaven National Laboratory is a science-based user facility devoted to nanotechnology research addressing challenges in energy security. Five internal research groups (Electronic Nanomaterials, Catalysis/Surface Science, Biology/Soft Materials, Electron Microscopy, and Theory/Computation) accompany a broad portfolio of scientific capabilities and an active external user program. I will provide an overview of the CFN facilities, which are accessible at no cost to users via a peer reviewed proposal process.
Our research program in Electronic Materials incorporates nanostructured materials with precisely defined and tunable internal dimensions as experimental platforms for understanding and improving electronic device performance. We are pursuing self-assembling materials as fabrication tools because of their ability to autonomously form patterns at sub-lithographic feature sizes (<20nm) and pitches (<40nm), and with a high density of features (~10^11/cm2). Although patterns formed via self assembly typically have only limited positional order and a high density of defects, they are nevertheless well-suited to large-area device applications such as solar cells. I will present our research progress implementing self-assembly approaches into nanostructured solar cell designs, as well as our previous successful implementation of self assembly in high-performance semiconductor devices.
3:00 - 4:00pm, Haus Conference Room - 36-428.

BASF Advanced Research Initiative presents:
Dr. Viola Vogel: Catch Bonds Enable Bacterial and Cell Adhesion Under Flow
5:00 – 6:00 pm | Pierce 209| Reception to follow in the Brooks Room
Abstract: How well does our intuition serve us when trying to prevent bacterial infections? If receptor-ligand complexes are being pulled apart by tensile forces, conventional wisdom implied that the lifetime of the complex would be shortened. As supported by many recent biophysical studies, force accelerates the probability of a ligand slipping out of the binding pocket. In contrast to these so-called slip bonds, recent data show that some receptor-ligand complexes can form catch bonds, bonds whose lifetime increases under tensile force. Some bacteria and cells take advantage of catch bonds to adhere to surfaces under fluid flow conditions. We will explore where such catch bonds can be found and how they work.

NRI e-Workshop: Nanoscale Thermal Engineering and Thermal Circuits with Graphene
Presented by Yong P. Chen of Purdue University
4pm ET / 3pm CT / 2pm MT / 1pm PT
Abstract: The excessive amount of heat generated in contemporary integrated circuits has become a major limiting factor in the continuation of Moore’s law scaling. In addition to developing novel computing devices (transistors using non-Si based materials, such as graphene, being one possibility) that generate less heat in the first place, finding strategies to manage or harness the heat is also important and urgently needed. Graphene could again bring various opportunities in this regard. This e-workshop will cover the following topics: 1) an overview of the superior thermal transport properties of graphene and the experimental measurement techniques. Applications in thermal interface involving graphene will also be discussed; 2) possibility to control the thermal transport by patterning graphene nanoribbons (GNR), revealed by molecular dynamics simulation. For example, both thermal rectification and negative differential thermal conductance can be realized. Thermal conductivity of GNRs is also shown to depend generally on edge chirality, impurities and isotope concentration. 3) an intriguing possibility of nanoscale control of heat flow is to use heat itself as a computational variable to perform information processing in appropriately designed nanostructures and architectures. Features and issues with such a “thermal logic” will be discussed.
Yong P. Chen received an M.Sc in mathematics from MIT and a PhD in experimental solid state physics from Princeton University. He is currently the Miller Family Assistant Professor of Nanoscience and Physics at Purdue University, with also a graduate faculty appointment in Electrical and Computer Engineering.
