Аннотация
In this paper, we consider the frequency dependence of the resistance of PbTe films. Establishing that the resistance of films containing an excess of lead up to 0.2 wt% decreases with increasing frequency of the supply voltage, and for samples containing more than 0.2 wt%, an increase in resistance is observed. At ω=3 105, the difference in the resistance of the films decreases significantly and the resistance weakly depends on the frequency of the alternating signal
