| abstract |
A multilayer plate for X-ray imaging is provided, which includes a substrate, a biasing electrode and a selenium-based membrane sandwiched between the substrate and the biasing electrode. The selenium-based membrane comprises a thick photoconductive layer of doped amorphous selenium and one or two thin buffer layers. One of the buffer layers is an amorphous arsenic triselenide layer positioned between the photoconductive layer and the substrate, and the other buffer layer is a unipolar conducting layer of alkali doped selenium positioned between the photoconductive layer and the biasing electrode. Preferably both layers are included. A method of producing such multilayer plates is also disclosed. |
