Growth of Single-Crystal VO2 Nanowires
H. Park and B.I. Halperin
(a) High resolution TEM image of a representative VO2 nanowire, illustrating lattice fringes.
(b) Diagram of a nanowire with the growth surfaces indicated.
Synthesis of single-crystal VO2 nanowires was achieved using a
simple vapor transport method in a tube furnace. VO2 is an attractive
material for a Mott field effect transistor, where the channel undergoes
an electrically driven Mott metal-insulator transition.
