We demonstrated a single resistance jump with orders of magnitude changes caused by a metal-insulator transition (MIT) in one domain in single-crystal VO2 nanowires with a 20 nm electrode gap. The nanowires were prepared from VO2 thin films on TiO2 (001) substrates and can provide numerous devices on a monolithic substrate using desired designs with precise positioning. The transport behavior of a single domain provides a simple understanding of the MIT and will apply an effective homogeneous electric field to a VO2 channel, aiding the development of Mott field-effect transistors and other devices using electronic phase changes.
