Abstract

The rectifying propertics of a diode made from a cupric selenide sample in contact with magnesium were examined under low frequency A. C. conditions. The observed time dependence of the current through the diode and its current-voltage characteristic were explained considering CuSe and Mg as components of a tamishing reaction under the electric field. As a result of this reaction, a Jayer of highly resistive magnesium selenide appeared. The change of its thickness led to rectification. Derived equations describe the experimental facts with satisfactory agreement. The ionic conductivity of MgSe was found to be 2.3 · 10^-6 Ω^-1 cm^-1 at room temperature.
