Achieving High Responsivity and Detectivity in a Quantum-Dot-in-Perovskite Photodetector.
Nano letters (Print), 2023This work reports on quantum dots (QDs) in perovskite photodetectors showing high optoelectronic performance via quantum-dot-assisted charge transmission. The self-powered broad-band photodetector constructed with SnS QDs in FAPb0.5Sn0.5I3 perovskite can

Abstract The chapter covers photodetectors for photons in the optical and near UV range (about 200 nm to 700 nm). Important for particle and astroparticle experiments are photodetectors which detect light generated in scintillation or Cherenkov detectors, for example.

Journal of Nanoscience and Nanotechnology, 2010
The use of nanowires and nanowire structures as photodetectors is an emerging research topic. Despite the large amount of reports on nanowire photoresponse that appeared in the literature over the last decade, the mechanism leading to high photosensitivity and photoconductive gain in high aspect ratio nanostructures has been elucidated only recently ...

Proceedings of the IEEE, 1966
This paper is intended as a status report on high-speed detectors for the visible and near-infrared portion of the optical spectrum. Both vacuum and solid-state detectors are discussed, with the emphasis on those devices which can be used as direct (noncoherent) detectors of weak optical signals modulated at microwave frequencies.

Ultraviolet detection is overriding priority in many military and civilian fields. A photodetector can be effectively enhanced by introducing piezo‐phototronic effect, pyro‐phototronic effect, and localized surface plasmon resonance (LSPR).

Advancements in exploring new chiral perovskites are highly demanded to improve the circular polarized light (CPL) detection efficiency to date. Reduced-dimensional (quasi-2D) perovskites thus emerged as the most promising candidates due to its appealing
