Computerized apparatus for thermally stimulated current (TSC) measurements.

A computer-controlled apparatus for thermally stimulated polarization and depolarization current (TSPC/TSDC) measurements over the temperature range -196 to 250 °C is described. The instrument is designed to combine state-of-the-art current sensitivity with computerized data acquisition and reduction. The apparatus is capable of detecting small (as low as 0.1 ppm) dipole concentrations (charge carriers) in solid dielectrics with the application of moderate electric fields (2–5 kV/cm).
