Pyroelectric & TSDC Depolarization Current Analyzers

Thermally Stimulated Depolarization Current (TSDC) and pyroelectric measurement systems evaluate spontaneous polarization changes, trapped space charge distributions, and dipole relaxation kinetics in functional dielectrics, ferroelectrics, and electret polymers. Monitoring sub-picoampere depolarization currents during linear heating sweeps quantitatively extracts activation energies and trap depth distributions.

The MatMeas pyroelectric platform, centered on the TSC-6520 spectrometer, integrates high-sensitivity femto-to-picoampere electrometry, high-vacuum specimen environments, and precision PID linear heating stages (-160°C to 450°C / 1000°C). The system enables complete TSDC, TSIC, and direct dynamic pyroelectric coefficient extraction, providing essential characterization for high-voltage dielectric insulation, energy harvesting materials, and uncooled infrared sensor research.
