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.
