Thermally stimulated depolarization of glassy As2S3

Decay of dark polarization in glassy As₂S₃ is investigated by thermostimulated depolarization (TSD). An attempt is made to analyse the observed maximum at about 360 K. To get more insight into the TSD phenomena, dc conductivity measurements at corresponding temperature are also presented. It is not possible at present to identify the trapped species responsible for the non-uniform polarization, despite finding that identical traps are active in both surface and bulk trapping.
