Photoconductive gain formula
WebThe photoconductive gain (G) represents the number of carriers generated per incident photon at a certain wavelength. (31) The relationship between R and G can be converted using the following formula (32) Webphotoconductive materials through modifications made to the chemical composition of the detector. For a given type of photoconductor material, at a given level of illumination, the …
