Abstract

A new method called the `Mirroir Method' for characterization of charging properties of insulators is presented. This method consists in the characterization of electrical potential formed after irradiation of a sample with 30 kV electrons in a scanning electron microscope. Analytical and numerical calculations allows to relate the electrical potential with intrinsic properties of materials such as the dielectric constant. Experimental results on various materials are well fitted by the models. The role of contamination layers is underlined. Relation between charging and mechanical properties are described owing to friction experiments.
