(Department of Physics, Kyung Hee University) ; Shin, H.W. As nouns the difference between phototransistor and photodetector is that phototransistor is any semiconductor device whose electrical characteristics are light-sensitive while photodetector is any device used to detect electromagnetic radiation. Thus, ITO/BFO(20)/Al photodetector with thick active layer shows low photoresponse characteristics. Furthermore, these two merits of narrowband and TPA characteristics are utilized to encrypt the photo-communication based on the above photodetectors. This article discusses what is a photodiode, working principle of photodiode, modes of operation, features, V-I characteristics and its applications Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.
