The further characterization of charge dynamics in non-conductive materials using the electron beam of the scanning electron microscope requires knowledge of the beam current and the injected charge densities. We report in this work an experimental p

To characterise insulating materials, measurements of their ability to trap or release injected charges have been developed recently by induced charge measurement (ICM). This new technique allows to investigate the charging properties of bulk or thin

It is now recognized that the internal energy of insulating materials is greatly affected by the presence of trapped charges. In particular this feature was recently analysed from Differential Scanning Calorimetry (DSC) measurements on polymers charg

A polycrystalline ceramic (Y/sub 2/ O/sub 3/ + 1 at.% La) has been charged under electron irradiation. The specific heat C/sub p/ of both an uncharged and of a charged sample has been measured by the microcalorimetric technique, showing that C/sub p/

We investigate the dopant effect of silver on detrapping charge properties in charged alumina samples. This effect is studied by measurement of the variation of specific heat, as a function of the temperature, correlated with the characterization of

Dielectric behavior of insulators can be explained using the space charge physics based on the concept of polarons. The local variation of polarisability due to crystal defects is responsible for trapping charges. In polycrystalline ceramics, point a
