Summary: The study reveals that the photoresponsivity of n-SnO2/p-Si heterojunction-based photodetectors reaches its maximum value at low incident power intensity, becoming almost independent of it. Detailed analyses of incident power intensity and dark current can be used to extract the maximum attainable photoresponsivity limit of the devices. This knowledge can be applied to extract the maximum photoresponsivity value for other heterojunction-based UV photodetectors.

Summary: We report a high-performance gas sensing strategy for the selective detection of Listeria monocytogenes, which is realized using n-CdO/n-SnO2 hetero-nanofibers with controllable compositions. The CdO/SnO2 nanofibers show enhanced 3H-2B sensing properties due to the modulation of n-CdO/n-SnO2 heterojunctions and the doping effect of Cd2+ ions. The variation of Cd/Sn molar ratios significantly affects the sensing performance, and 5 mol% CdO/SnO2 nanofibers exhibit the best response to 5 ppm 3H-2B at 260 degrees C, along with excellent stability and selectivity.
