Electronic properties of chalcogenide glasses and their use in xerography
An overview of the xerographic process and the relevant physical phenomena involved in the formation of the latent image is presented. Emphasis is on the electronic properties of a-selenium but some properties of other disordered solids will be mentioned in order to amplify features general to the disordered solid state. Specifically the discussion includes a description of the Onsager mechanism of charge generation, transient dispersive transport, and recent models of defects in chalcogenide glasses.
