Metal Oxide Nano‐Interface Boosting the Deep Ultraviolet Adjustable Noise‐Filtering In‐Sensor Computing

Advanced Materials, EarlyView.
We show that sol‐gel‐fractured indium–magnesium oxide combines deep‐ultraviolet responsivity, high carrier mobility, and an excellent memory dynamic range. This unique materials platform enables deep‐ultraviolet long‐afterglow light‐emitting devices with multifunctional integration.

Spike‐Type Band Alignment via in2Se3/CuI Charge‐Transport Engineering Enables 26% Efficient Lead‐Free RbSn0.5Ge0.5I3 Perovskite Solar Cells

Advanced Materials Interfaces, EarlyView.
A lead‐free and Cd‐free RbSn₀.5Ge₀.5I3 perovskite solar cell is optimized through In2Se3/CuI charge‐transport engineering using SCAPS‐1D. Spike‐type band alignment suppresses interfacial recombination, enhances charge extraction, and achieves a power conversion efficiency of 26.01%, providing an effective strategy for high‐performance and ...

Band Alignment of Grafted Si/Ge0.89Sn0.11 Heterojunction Determined by X‐Ray Photoelectron Spectroscopy

Advanced Materials Interfaces, EarlyView.
ABSTRACT We investigate the band alignment of a monocrystalline grafted p‐type Si/Ge0.89Sn0.11 heterostructure using X‐ray photoelectron spectroscopy (XPS). The bandgap of the Ge0.89Sn0.11 epilayer of 0.50 eV was first determined and cross‐verified using photoluminescence spectroscopy, infrared transmission, and theoretical calculation.
