ABSTRACT
This update chapter is confined to wide-area amorphous silicon photoreceptor drums capable of receiving an electrostatic latent image for the purpose of development and transfer to a wide-area receiver-typically paper. For photoreceptor applications, a-Si is used only on rigid drums. There would be great demand for photoreceptor belts, but a-Si, at the thickness required, does not flex enough to be usable on a belt. Amorphous silicon in photoreceptor applications must be hydrogenated as explained in Chapter 16. This update chapter will therefore cover only advances in a-Si:H photoreceptor drums. For easier reading, “ hydrogenated” and “ :H” will be omitted and this material will be abbreviated as “ a-Si” in the text.
