“…The superconducting hypothesis [4] seems to be promising in explaining the results obtained in [1][2][3] as well as the switching behavior of NG films and our results described elsewhere [13][14][15][16]. Of course this hypothesis now is far from its proof.…”

“…Attention has been paid to the conductivity switching behavior in the carbon graphite-like materials. Antonowicz et al more than 30 years ago investigated the conductive properties of the glassy carbon [1] and its evaporated deposits [2] and has found out the effect of conductivity jump up to three orders of magnitude under critical current of the order of tens of milliamps. The change of conductivity was reversible, and the relaxation time was about some days.…”

The structure and properties of nanographite films useful for applications in solid state devices are described. The possibility to use low conducting state of nanographite film for detecting radiation in the segmented solid state detectors is considered. Other interesting phenomena include the field effect conductivity switching which can be used in contactless current limiters and circuit breakers, therf-to-dcconversion which can be utilized in microwave and photo detectors, and light emitting subsequent to the conductivity switching with possible application as light sources. The possible underlying gears of the mentioned effects are discussed.

“…Electrical conductivity of polyfurfuryl alcohol heated a t 600 "C increases by many orders of magnitude in comparison with that heat-treated at 400 "C [8]. I n addition in high electric fields conduction electrons are produced by the Frenkel-Poole mechanism and by injection.…”

“…Therefore, below heat treatment temperature (600 "C) one can expect only reversible changes in resistivity due to heating, a t higher temperatures an irreversible decrease in resistivity is possible, but experiment shows something completely different. The highly conducting state, once generated, persists for a few days up to one week, it decays slowly and finally the original resistance is re-established [8]. Therefore, the highly conducting state in carbon cannot be explained by thermal effects.…”

The effect of electrical resistivity switching in nano -graphite films is described. In difference with cases published elsewhere the switching in nano -graphite films occurs from stable high conductive to metastable low conductive state. Critical current of switching varies in the range 0.01-0.5A and can be increased up to values appropriate for using of nano -graphite samples in power grids as contact-less current limiters and circuit breakers. The possible mechanisms of switching phenomenon in nano -graphite films are discussed.Physical and electromagnetic properties of the carbon and its derivatives are the subjects of constant interest and extensive studies for many years. Attention has been paid to the switching behavior in the carbon graphite like materials. K. Antonowicz more than 30 years ago investigated the conductive properties of the glassy carbon [1] and its evaporated deposits [2] and has found out the effect of jump of conductivity up to three orders of magnitude. The change of conductivity was reversible, and the relaxation time made some days.B.Z.Jang and L.Zhao also studied the switching behavior of carbonized materials [3]. They study the partially carbonized polyacrylnitride fibbers, which were observed to undergo a resistivity change between 2 and 4 orders of magnitude at a transition temperature typically in the range of 98°C to 200°C. The current-voltage curves exhibited an initial supercurrent-like increase, followed by a rapid drop to a high resistance state, and then a rise in current
