TL;DR: A comprehensive review on the state-of-the-art research activities in the UV photodetection field, including not only semiconductor thin films, but also 1D nanostructured materials, which are attracting more and more attention in the detection field are provided.

TL;DR: Fabrication of a high-temperature deep-ultraviolet photodetector working in the solar-blind spectrum range (190-280 nm) is a challenge due to the degradation in the dark current and photoresponse properties, but β-Ga2O3 multi-layered nanobelts with (l00) facet-oriented were demonstrated for the first time to possess excellent mechanical, electrical properties and stability at a high temperature inside a TEM studies.

TL;DR: Electrochemical-coupling layer-by-layer (ECC-LbL) assembly is introduced as a novel fabrication methodology for preparing layered thin films to covalently immobilize functional units into thin films having desired thicknesses and designable sequences for both homo- and heteroassemblies while ensuring efficient layer-to-layer electronic interactions.

TL;DR: In this article, a new UV-A photodetector based on K2Nb8O21 nanowire is successfully fabricated for the first time, and the potassium niobate is synthesized using a facile molten method.

TL;DR: In this article, the authors comprehensively investigated the performance of diamond DUV detectors fabricated from various kinds of single crystal diamonds such as boron-doped diamond homoepitaxial layer, intrinsic diamond homophase, and single crystal diamond substrates.
