中文摘要	We report on local probe measurements of current-voltage and electrostatic force-voltage characteristics of electric-field-induced insulator to metal transition in VO(2) thin film. In conducting AFM mode, switching from the insulating to metallic state occurs for electric-field threshold epsilon similar to 6.5 x 10(7) Vm(-1) at 300 K. Upon lifting the tip above the sample surface, we find that the transition can also be observed through a change in electrostatic force and in tunneling current. In this noncontact regime, the transition is characterized by random telegraphic noise. These results show that electric field alone is sufficient to induce the transition; however, the electronic current provides a positive feedback effect that amplifies the phenomena.
