“…Since about 1980, powerful experimental methods have been developed for measuring charge distributions in dielectrics with a resolution of w 1 pm in the thickness direction [1,3]. Most prominent are thermal and acoustic techniques where electrical signals are generated in the sample due to heat diffusion or propagation of a pressure discontinuity, respectively.…”

A literature review on space-charge electrets, covering the time period 1987 to 1996, is presented. The review starts out with a discussion of new inorganic and organic electret materials which also includes silicon based single and double layers. This is followed by a review of recent work on methods for measuring charge distributions. New results obtained with these methods on a number of differently charged materials are surveyed, together with data for charge transport and charge decay. Of particular significance is the superb charge storage capability of silicon dioxide/silicon nitride double layers which was discovered only very recently. The review closes with a survey of new, or improved electret applications.

“…Many attempts have been made in order to elucidate the origin of complex TSDC peaks. They are based on the behavior of the TSDC peaks as a function of the polarization parameters [8,20,21]. Several methods were used to decompose the experimental complex bands into limited number of elementary peaks [18,22].…”

“…In addition, a convenient method for further identifying the character of TSC peaks is to analyze the relationship between the peak intensity and polarization voltage. 14,15 The intensity of the glass transition linearly increased with the polarization voltage, whereas the intensity of the transition increased linearly first and then leveled off. 14 Consequently, the PDLC film with an LC content of 40 wt % was treated at various polarization voltages, and their resultant TSC spectra are shown in Figure 3.…”

“…Recently, the thermal stimulated current (TSC) method has been applied and proven to be a useful technique to study the coupling characteristics, the thermal transitions, and the discharge of space charges of polymers and blends. [13][14][15][16] When an electrical field is applied to hybrid materials such as PDLC, space charges are created and trapped in the interfacial regions between heterogeneous phases. The unique character of the discharge behavior of space charges shown in TSC traces offers a qualitative understanding of the interfacial character between heterogeneous phases.…”
