There are two types of thermally stimulated current (TSC) measurement methods, classified by the origin of the current. One is generated by the detrapping of charges. The other one is generated by depolarization. The latter is frequently called thermally stimulated depolarization current (TSDC). This part of IEC 62607 focuses on the latter method, and specifies the measurement procedures to be developed for determining polarization properties of metal-oxide interfacial devices.

This document includes:

  • outlines of the experimental procedures used to measure TSDC,

  • methods of interpretation of results and discussion of data analysis, and

  • case studies.
