Broadband Impedance Spectroscopy

Impedance spectroscopy is a powerful tool used to characterize semiconducting and dielectric materials as well as ionic and mixed electronic-ionic conductors. The technical base of the laboratory allows measurements of complex impedance in frequency range from 0.1 Hz to 10 GHz and temperature range from 300 K to 1200 K.

Object of Investigation

Our sample holders are adapted for studies of single crystals, ceramics, glasses, interfaces between different materials as well as integrated circuit devices, which operate under elevated temperatures.

High Temperature Measurements

Up to 2 MHz measurements we use 4-electrode setup. Up to 10 GHz measurements we use a coaxial waveguide assembly. Our sample holders are made of platinum covered refractory ceramics, so we are capable to perform accurate impedance spectra measurements with relatively small systematic errors up to 1200 K.


Our laboratory is open for collaborations in all physical, chemical and technical fields of science and industry.
