Unraveling the atomic mechanism of the disorder–order phase transition from γ-Ga2O3 to β-Ga2O3

APL Materials
In this paper, we employ in situ transmission electron microscopy to study the disorder–order phase transition from amorphous Ga2O3 to γ-Ga2O3 and then to β-Ga2O3.

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

High field-emission current density from β-Ga2O3 nanopillars

, 2019
Field emission from gallium oxide (β-Ga2O3) nanopillars, etched by Ne+ ion milling on β-polymorph (100) single crystals, is reported. A stable field emission current, with a record density over 100 A/cm2 and a turn on field of ∼ 30 V/μm, is achieved.

Three‐dimensional hybrid perovskite heterostructure single crystals toward highly efficient x‐ray detectors

InfoMat, EarlyView.
This study presents for the first time a self‐assembled three‐dimensional perovskite heterojunction single crystal with organic cations and Pb coordination, (MHy)2Pb(2)Cl4·Pb(1)Cl2 (MPC). The MPC possesses carriers with different conformations and undergoes an ordered–ordered structural transition as the temperature increases, which ultimately realizes

Programmable solar‐blind ultraviolet sensors enabling integrated single‐pixel sensing and neuromorphic processing

InfoMat, EarlyView.
A Schottky photodiode based on (Al0.14Ga0.86)2O3 was developed, in which the sensing and processing functions were temporally decoupled through bias voltage modulation. By integrating single‐pixel imaging with a reservoir computing architecture, a comprehensive intelligent vision system was constructed.
