Abstract Earth‐abundant amorphous nanomaterials with rich structural defects are promising alternative catalysts to noble metals for an efficient electrochemical oxygen evolution reaction; however, their inferior electrical conductivity and poor morphological control during synthesis hamper the full realization of potency in electrocatalysis. Herein, a rapid surface‐guided synthetic approach is proposed introduce mixed‐metal oxyhydroxide overlayers on ultrathin Ni‐doped MnO 2 (NiMnO )...

An ultraviolet photodetector was fabricated on MgZnO thin film grown by metal-organic chemical vapor deposition. The peak response of the device centers at 238 nm and cutoff wavelength is 253 nm. responsivity 129 mA/W 15 V bias, UV/visible reject ratio 4 orders magnitude. Internal gain due to hole trapping interface that brings low speed. Native defects Au/MgZnO degrade barrier effect, which caused large dark current high visible response.

Abstract Black phosphorus (BP) has emerged as a promising two-dimensional (2D) material for next generation transistor applications due to its superior carrier transport properties. Among other issues, achieving reduced subthreshold swing and enhanced hole mobility simultaneously remains challenge which requires careful optimization of the BP/gate oxide interface. Here, we report realization high performance BP transistors integrated with HfO 2 high- k gate dielectric using low temperature...
