WebJan 1, 2024 · Thus, only amorphous or polycrystalline (poly)photoconductors are currently practical for use in large-area x-ray imaging detectors. Amorphous selenium (a-Se) is one of the most highly developed photoconductors for large-area detectors due to its commercial use in photocopiers and laser printers as an electrophotographic photoreceptor . In fact ... WebFeb 16, 2024 · For the n-type photoconductors, the n + regions were created by diffusion doping, while for the p-type photoconductors, boron implantation was employed to create the p + regions. Afterward, the thermal oxide was entirely removed from the front and back side of both n- and p-type wafers by BHF etching. This was followed by aluminum (Al) film ...

WebJan 11, 2024 · The photodiode. The photodiode is a two-element P-N or PIN junction that is exposed to light through a transparent body or cover. When light strikes the junction, a current or voltage is developed depending on the mode of operation. The photodiode operates in any of three modes depending on the biasing applied to it.
