The expressions for the concentration of trapped electrons in materials, electrical field strength and total charge are derived by solving total current equation at stationary state. Space charges are determined experimentally by using thermally stimulated depolarization current (TSDC) method, and TSDC spectrums are illustrated for investigated materials.eninfo:eu-repo/semantics/closedAccessDischargeConference Object491494WOS:000261588200122N/A
