The effect of switching electrical resistivity in nanographite films is described. In contrast to the cases published earlier, switching in nanographite films occurs from a stable state with high conductivity to a metastable state with low conductivity. The critical switching current varies in the range of 10–500 mA and can be increased to values of 100 A or more, suitable for using nanographite switches in intelligent electric networks as contactless current limiters and circuit breakers. Possible mechanisms of the switching phenomenon in nanographite films are discussed. |
