Carbon films were obtained by magnetron sputtering of graphite in an argon atmosphere on various metal substrates. As a result, a “metal-semiconductor” junction is formed due to the fact that the temperature dependence of the film resistance is of a semiconductor nature. The current-voltage characteristics of the junction were studied at various ambient temperatures, and the degradation of its electrical properties over time was discovered.

Углеродные пленки были получены методом магнетронного распыления графита в аргоновой атмосфере на различных металлических подложках. В результате образуется переход “металл-полупроводник” т.к. температурная зависимость сопротивления пленок носит полупроводниковый характер. Были изучены вольт-амперные характеристики перехода при различных температурах окружающей среды, а также обнаружена деградация его электрических свойств со временем.
