Photoconductive mode
WebApr 10, 2024 · Here, the photodetector acquires a higher responsivity (0.36 A W −1) and a lower NEP (88.5 pW Hz −1/2) at 0.3 THz. Compared with the previous detector, the sensitivity of the asymmetric short channel detector at 0.1 and 0.3 THz is improved by an order of magnitude. WebPhotodiodes can be used under either zero bias (photovoltaic mode) or reverse bias (photoconductive mode). In zero bias, light falling on the diode causes a current across the device, leading to forward bias which in turn induces "dark current" in the opposite direction to the photocurrent. This is called the photovoltaic effect, and is the ...
