INJECTION AND TRANSPORT IN GLASSY POLYMERIC COATINGS

Organic electrophotographic receptors have been enabled by the develop ment of unique classes of high dielectric strength glassy polymer coat ings, which, though insulating, are nevertheless capable of transporti ng injected charge with relatively high mobility and negligible loss t o deep traps. Key features of electronic transport in these materials and the underlying physics are described. Additionally, it is demonstr ated that these trap-free transport polymers provide a unique venue fo r the exploration of contact behavior and the factors controlling inje ction efficiency In disordered organic solids.
