The system for complex electric permittivity measurements of solid-state materials in the range of 20 Hz to 1 GHz

摘要

We worked out a fully computerised system for complex electric permittivity measurements of solid-state materials in the frequency range of 20 Hz to 1 GHz and temperature from 77 K to 430 K. The measuring system contains three main parts: (i) metrological, (ii) temperature controller, (iii) sample holder with a specially designed Dewar container and a level controller of liquid nitrogen.
