Considerations on using Thermal Pulses for Space Charge Measurements in Medium Thickness Insulating Samples

In this paper, the responses to the application of thermal pulses on space charge containing medium thickness polyethylene samples (50-100 µm) coated with thin and thick semicon electrodes is studied through simulations. Surface temperature, signal amplitude and signal dynamics are analyzed in order to assess the feasibility of experimental setups without affecting the state of the sample and also allowing high sensitivity/resolution measurements near the interface between a semiconductor layer and an insulating layer.
