Microwave absorption (MWA) enables contactless measurements of electronic transport properties in solids. MWA is the only method for studying the lifetimes and mobilities of the photogenerated charge carriers that depend on the recombination process of photoelectrons. Therefore MWA is a powerful tool to understand the influence of phase structures of point defects like Y−, Ir3+, Pb++, Cu++, etc., dislocations; and chemical and dye sensitization on the formation of latent image specks.
