The frequency possibilities of metal-oxide varistors are investigated. An expression is deduced for the limiting frequency f o of their application. It is also expressed in terms of the catalogue data of commercial varistors or by means of the parame

Using reflection methods in the plasma frequency range, nonparabolic valence bands of solid solutions Pb1—xSnxTe with composition near the inversion point of the bands (x = 0.55, 0.6, 0.65) are investigated. The Hall concentration of the samples ar
