Photoresponse Properties of Ambipolar Transport in WSe2 Field‐Effect Transistors

Advanced Electronic Materials, EarlyView.
This study explores the photoresponse of WSe2 ambipolar field‐effect transistors, which exhibit unipolar, saturation, and ambipolar transport regions. Light illumination induces a shift of critical voltage with enhanced photocurrent generation driven by the photogating effect without the material degradation seen in avalanche photodetectors. This study

High‐Performance Solar‐Blind Photodetectors Enabled by Post‐Annealing Optimization of Solution‐Processed Ga2O3 Films

Advanced Electronic Materials, EarlyView.
Post‐annealing atmosphere and temperature are optimized to regulate oxygen‐related defect states in solution‐processed Ga2O3 films. The optimized H2/N2 annealing enables enhanced photoconductive gain while maintaining low dark current, leading to high‐performance solar‐blind photodetectors with a responsivity of 7.5 × 102 A W−1 under 254 nm ...

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2

Advanced Electronic Materials, EarlyView.
ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\
