Phosphorene, a elemental 2D material, which is the monolayer of black phosphorus, has been mechanically exfoliated recently. In its bulk form, black phosphorus shows high carrier mobility (∼10,000 cm(2)/V·s) and a ∼0.3 eV direct band gap. Well-behaved p-type field-effect transistors with mobilities of up to 1000 cm(2)/V·s, as well as phototransistors, have been demonstrated on few-layer black p...

clavulanic acid is produced industrially by fermentation of streptomyces clavuligerus and researches have increased its production by strain improvement, recombinant dna technology, and media composition and growth condition optimization. the main objective of this study was to increase the level of clavulanic acid production from streptomyces clavuligerus (dsm 738), using uv irradiation. after...

For wavelength-selective photodetection or color discrimination, organic photodetectors (OPDs) can provide significant advantages as solution processability, chemical versatility and functionality. To eliminate the need for commonly used filters, development...

Correction for ‘Electrical characteristics and photodetection mechanism of TiO 2 /AlGaN/GaN heterostructure-based ultraviolet detectors with a Schottky junction’ by Teng Zhan et al. , J. Mater. Chem. C 2023, 11 1704–1713, https://doi.org/10.1039/D2TC04491A.

We show a hybrid structure consisting of Si film with photonic crystal surface and random triangular gold grooves reflector at the bottom, which is capable of realizing efficient, broad-band, wide-angle optical absorption. It is numerically demonstrated that the enhanced absorption in a broad wavelength range (0.3-9.9 μm) due to the scattering effect of both sides of the structure and the creat...

The hadronic calorimeter for the CMS experiment requires photodetection in a 4 Tesla magnetic field. This, plus high neutron radiation and a 25 ns bunch-crossing, necessitated the development of a new type of high-rate multi-channel hybrid photodiode. As our specifications became tighter, design changes in the diode structure and surface treatment became necessary, resulting in a better product...
