Lecture

Optical Detectors: Photoconductors

Description

This lecture covers the operation of photoconductors, focusing on the inherent characteristics and advantages of using materials like cadmium sulfide (CdS) and cadmium selenide (CdSe). It explains the principles behind the generation of electron-hole pairs, the impact of carrier lifetime on sensitivity, and the trade-offs between speed and sensitivity in photoconductors.
