Abstract Self-assembled AlGaN nanowires (NWs) are regarded as promising structures in the pursuit of ultraviolet photodetectors (UV PDs). However, NW-based PDs currently suffer from degraded performance partially due to existence outstanding surface-related defects/traps a result their large surface-to-volume-ratio. Here, we propose an effective passivation approach suppress such surface states...

Kesterites are currently viewed as one of the most promising candidates for earth abundant and benign elements to substitute critical raw materials in photovoltaic technologies may also be suitable low-noise, room-temperature, self-powered photodetectors. However, while impact buffer layers on kesterite solar cell efficiency has been an active area investigation, links between photodetector per...

In this study, an in-situ piezoelectric effect is integrated into a photoactive region to develop self-powered ultraviolet photodetector based on p-n junction of ZnO@Polyvinylidene fluoride (PVDF) and poly [9,9-dioctylfluorene-co-N-[4-(3-methylpropyl)]-diphenylamine] (TFB). A ZnO@β-PVDF nanocomposite fabricated using PVDF with the β-phase as polymer matrix ZnO nanoparticles fillers. The strong ...

The resistive microbolometer fabricated by using CMOS technology can be monolithically integrated with the readout circuit but usually performs poorly in responsivity and detectivity. In this paper, poly-Si Al grating structure is demonstrated standard process. simulation results show that not only are surface plasmon polaritons generated at interface of SiO <sub xmlns:mml="http://www.w3.org/19...

This work presents the high-performance Si/SiO2 distributed Bragg reflector (DBR)-integrated lateral germanium (Ge) p-i-n photodetectors (PDs) for atmospheric gas sensing and fiber-optic telecommunication networks in short-wave infrared (SWIR) regime. In addition, this study also proposes an optoelectronic compact small-signal noise equivalent circuit model (SSNECM) of designed device to comput...
