AMORPHOUS-SELENIUM BASED X-RAY DETECTOR FOR DECREASING LEAKAGE CURRENT

摘要

The present invention relates to an X-ray detector based on amorphous selenium, facilitating introduction of a pair of electron-holes generated by an X-ray in an amorphous selenium layer; and preventing a leakage current of an electron injected from a metal electrode to the amorphous selenium layer by an electric field through band gap engineering without doping As or CI to the amorphous selenium.
