Liquid Bismuth Catalyst Enables High‐CO‐Selectivity in CO2 Hydrogenation

Advanced Science, EarlyView.
This work introduces a dynamic liquid bismuth catalyst for efficient CO2‐to‐syngas conversion. Stabilized molten Bi nanodroplets on a defective VOx support enable a reversible Bi3+/Bi0 redox cycle at moderate temperatures. Mechanistic insights reveal that Ni‐Bi dual sites synergistically activate H2 and cleave CO2, leading to high CO selectivity ...

Synergistic Pyro‐Phototronics and Structural Anisotropy in CsAg2I3/GaN Heterostructures for High‐Performance Polarization‐Sensitive UV Photodetectors

Advanced Science, EarlyView.
The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.

Ultrawide bandgap LiGa5O8/β-Ga2O3 heterojunction p–n diodes [PDF]

APL Electronic Devices
Ultrawide bandgap (UWBG) semiconductor β-phase Ga2O3 has attracted significant interest for potential power electronics applications. This, however, is hindered by the lack of effective p-type dopants in β-Ga2O3.

Low In solubility and band offsets in the small-$x$ $\beta$-Ga$_2$O$_3$/(Ga$_{1-x}$In$_x$)$_2$O$_3$ system

, 2014
Based on first-principles calculations, we show that the maximum reachable concentration $x$ in the (Ga$_{1-x}$In$_x$)$_2$O$_3$ alloy in the low-$x$ regime (i.e. In solubility in $\beta$-Ga$_2$O$_3$) is around 10%. We then calculate the band alignment at
