Wafer‐Scale Bandgap‐Tunable MoS2/PbS Phototransistors Enabled by Solution Processing

open access: yesAdvanced Science, EarlyView.
This work advances bandgap‐tunable MoS2/PbS phototransistors by introducing lateral heterojunctions, which enable superior tunable bandgap (1.24–0.61 eV) via Type‐II alignment. Plasma‐enhanced solution processing ensures uniform 4‐inch wafer‐scale fabrication with 97% yield.

Interlayer Dzyaloshinskii–Moriya Interaction in Synthetic Ferrimagnets for Spiking Neural Networks

open access: yesAdvanced Science, EarlyView.
This work introduces a groundbreaking integration of asymmetric magnetic structures (synthetic ferrimagnets) and antisymmetric magnetic interaction (interlayer Dzyaloshinskii–Moriya interaction) for the first time. It addresses the critical challenge of IL‐DMI detection and shows the discovery of unprecedented analog‐like spin‐orbit torque switching ...

Ultrafine Ru‐M Alloy@S Vacancy‐Rich MoS2 Nanosheets With Bimetallic Active Sites for Efficient Hydrogen Evolution in Alkaline and Acidic Media

open access: yesAdvanced Science, EarlyView.
A USMR synthesizes ultrafine RuCo alloy on S‐vacancy‐rich 1T phase MoS2. This method enables rapid precursor mixing, instantaneous reduction, and uniform alloy dispersion while creating S vacancies. The synergy between Ru‐Co sites and defective MoS2 optimizes hydrogen kinetics, achieving a low overpotential of 31 mV@10 mA·cm‐2 in acid, providing a ...

Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

open access: yesAdvanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.
