Abstract

An automated setup for studying thermostimulated currents (TSC) in semiconductor and dielectric materials is made. Unlike the existing equipment, it enables TSC to be measured in vacuum in a broad range of the linear heating rates (0.01-10 °C/s) and temperatures (20-400 °С). The signal, detected by the setup, varies within 10-12 A to 10-7 A. An electronic control system was designed to control the heating process. A microcontroller was used for digital data acquisition, processing and transfer to a personal computer. Test measurements of thermostimulated conductivity currents (TSCC) were carried for a quartz single crystal.
