Abstract

The effect of electrical resistivity switching in nanographite films is described. In difference with cases published elsewhere the switching in nanographite films occurs from stable high conductive to metastable low conductive state. Critical current of switching varies in the range 10-500 mA and can be increased up to values appropriate for using of nanographite samples in power grids as contact-less current limiters and circuit breakers. The possible mechanisms of switching phenomenon in nanographite films are discussed.
