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.

Excited‐State Pathway Switching via Reversible Structural Phase Transitions in Sb3+‐Doped Cadmium Halides

Angewandte Chemie, EarlyView.
Octahedral (DFPD)6CdCl8:10%Sb and tetrahedral (DFPD)2CdCl4·H2O:5%Sb exhibit distinct luminescence dictated by coordination geometry. Solvent‐induced reversible phase transformation enables dynamic switching between yellow and deep‐orange emission. Combined experimental and computational studies elucidate the luminescence mechanisms, and the reversible ...
