Abstract :
Two modifications of the thermally stimulated depolarization current (TSDC) method are proposed to improve resolution and sensitivity of the method by connecting either a real capacitor or an additional resistor in series with the sample. It is shown experimentally that the high sensitivity in the TSDC method with the air gap can be obtained if the gap is substituted by the capacitor, while all advantages of the method remain in force. It was found that one could obtain in one experiment the data on the thermally stimulated conductivity (TSC) along with the TSD current, if the additional resistor is periodically switched on and off.
