WebPhotoconductive detectors have a bulk resistance which is temperature dependent. For lead salt photoconductive films this temperature dependency is typically on the order of 3 %/°C. The problem is that if the bulk resistance is changing due to temperature variations it can be indistinguishable from the photoconductive signal. Modulation of the ... WebThe controllable doping of S in a zeolitic In–Se host results in an optimal balance between resistivity, band gap, and carrier mobility, which finally results in an excellent X-ray detector with a high figure of merit for the mobility–lifetime product (7.12×10 −4 cm 2 V −1); this value is superior to that of a commercial α-Se detector ...
WebThe photoconductive detector is the most simple of the detector devices, where a single layer thin film or bulk material may be used. Schottky or ohmic contacts are then deposited to complete the device, with an example device structure shown schematically in Figure 12. The current density in the photoconductor will be given by (3) (4) WebFor a GaN UV detector, the maximum photoconductive gain G max of 763.71 was obtained at a voltage of 20 V and an incident light power of 15 nW. The MoS 2 visible detector achieved a G max of 183.88 at 3 V and an incident light power of 2 mW.
