Abstract
The experimental data on the measurement of resistance and electrical conductivity in a low-resistance mode of operation of a memristor based on germanium selenide with a self-directed conductive channel in the range of switching frequencies and temperatures are presented. In the frequency experiment, the switching frequency effect is conducted at room temperature in the range of 1 to 10 000 Hz. An experiment to study the effect of temperature on resistance and electrical conductivity is carried out in the temperature range –10–65°C at a switching frequency of 10 Hz. The aim of this study is to determine the activation energy of the formation of a conductive channel. It is shown that in the temperature range 22–65°C electrical conductivity obeys the Arrhenius law with an activation energy of 0.19 eV; at temperatures below room temperature, the electrical conductivity is insensitive to temperature changes. The reasons for the low value of the activation energy are discussed.
