At the same time, onedimensional GaAs nanowire as photosensors for infrared detection has been seldom studied. Single-mode fibers are standard. Here, the photodetector end of the fiber has been angle-polished to reduce optical back reflections to less than -35 dB. GaAs nanowires have widely applied in infrared devices in the past few years. The current-voltage characteristics of the device under UV illumination showed an enhancement that dark current. The dark current is about 58 μA, and the photocurrent is about 97 μA under a reverse bias voltage of 6 V. The photocurrent characteristic of photodetector is measured under 3 V forward biases and after 18 min it saturated.

Noise Characteristics of MgZnO-Based Metal–Semiconductor–Metal Photodetector Abstract: The noise characteristics of wurtzite MgZnO metal-semiconductor-metal photodetectors (PDs) are investigated by a proposed equivalent noise circuit model considering the effects of thermal noise and shot noise induced by the resistances and fluctuations of photogenerated carriers, respectively. Thus, ITO/BFO(20)/Al photodetector with thick active layer shows low photoresponse characteristics. Photoresistors, for instance, will change their resistance according the light intensity incident on the device. w.wang Fundamentally a photodiode is a current generator. The effect of grain boundary on the characteristics of poly-Si metal–insulator–semiconductor photodetector is investigated utilizing two-dimensional device simulator.In the investigation, the trap states in grain boundary are composed of two types: tail states and deep-level states, both of which consist of acceptor-like trap and donor-like trap. In this study, influence of rapid thermal oxidation RTO and embedding of gold nanoparticles on the performance of porous silicon photodetector synthesised by anodization technique were investigated. In this work, self-powered UV–visible photodetector characteristics of the polycrystalline BiFeO 3 thin film exhibiting pronounced photo-response under both UV and visible light are demonstrated. However, the performance of GaAs nanowire photodetectors is strongly limited by the problem of large surface state density. In the multimode models, a GRIN lens focuses the light onto the photodiode.
