Highly ordered perovskite nanowire (PNW) arrays are important building blocks for potential application in integrated optoelectronic devices due to their unique properties. Herein, a recordable digital versatile disk-assisted nanochannel-confined growth (NCG) strategy was developed large-scale of different kinds PNW with preferentially crystallographic orientation on various substrates.

Benefit from high quantum efficiency and low dark current, blocked-impurity-band (BIB) detectors have been the state-of-the-art choice in astronomy science. The temperature extrinsic-response-reduction mechanism BIB is vague for lack of pertinent research. We fabricated Si:P with a remarkable blackbody detectivity 2 × 1012 cm · Hz1/2/W at 4 K, V (blackbody 800 K). Both varying optoelectronic ch...

Wavelength tunable detectors are essential for capturing spectral information within diverse applications such as those related to object recognition and identification. Here, we present a generalizable design compact dual-band photodetector based on the integration of two back-to-back organic photodiodes that respond visible (400–700 nm) infrared light (700–1,400 nm). The polarity under extern...

CsPbCl3 perovskite is attracting increasing interest in ultraviolet (UV) detection due to its optical band gap and superior intrinsic optoelectronic properties. In this study, a novel one-step magnetron sputtering technique was applied for fabricating polycrystalline films on flexible plastic substrates with interdigitated contacts. The photoconductive response of 500 nm 1 µm thick pulsed light...

Abstract The structure of a gate-controlled graphene/germanium hybrid photodetector was optimized by splitting the active region to achieve highly sensitive infrared detection capability. strengthened internal electric field in split junctions enabled efficient collection photocarriers, resulting responsivity 2.02 A W −1 and specific detectivity 5.28 × 10 Jones with reduced dark current improve...

We have investigated the effect of Au nanoparticles on low frequency noise and current-voltage Au/Cu doped ZnO (Nps) based photodetectors (PDs). Besides, 1/f Cu is studied with without Nps conditions varied bias voltages. The codoped showed much lower higher normalized photocurrent to dark current ratio (NPDR) than undoped Nps. This enhancement may be attributed localized surface Plasmon resona...

Electrical detection of graphene plasmons is important for developing mid-infrared photodetection and sensing applications based on graphene.
