Abstract
Based on an analysis of the volt-ampere characteristics and temperature dependence of conductivity, the mechanism of current transfer is discussed in thin-film systems of metal/vanadium -phosphorus glass/metal. The conclusion is drawn that the magnitude of the current in samples obtained by sputtering of the glass on a “hot” backing (Tb = 200°C) is determined by the resistance of the volume of the glass film, but for samples sputtered on a “cold” backing (Tb = 30–90°C), by the resistance of the potential barriers at the metalglass interface. It is supposed that current transfer in a film of glass is accomplished by polarons of small radius.
