Silicon carbide is used in abrasives, in polishing and grinding. It is widely used in appliions calling for high endurance, such as automobile brakes, car clutches and ceramic plates in bulletproof vests. Electronic appliions of silicon carbide are as light emitting
The photodetector with a high UV-to-visible rejection ratio of up to 1 × 10 5 exhibits a low dark current of <2 pA at room temperature under 10 V bias. The photo-responsivity of the photodetector gradually increases as a function of applied bias, resulting in a photodetector quantum efficiency exceeding 100% at above medium bias.
2020/8/17· Poor sensitivities and low efficiency undermine the performance of ultraviolet (UV) sensors deployed in diverse appliions.
