Abstract
We report here the effect of poly(styrene-acrylonitrile) copolymer interface barrier layer films on the charge storage and decay characteristics of amorphous selenium (a-Se) films studied by the thermally stimulated discharge current and potential decay techniques, respectively. Incorporation of copolymer interface barrier layer reduces the charge storage capacity/built-up of residual potential in a-Se film and enhances its x-ray sensitivity. These effects have been attributed to the blocking and field assisted enhanced mobility role of the copolymer interface barrier film.
