Multidimensional Sensing in Flexible Violet Phosphorus Photodetectors Driven by the Bulk Photovoltaic Effect

ABSTRACT The bulk photovoltaic effect (BPVE) generates zero bias photocurrents in systems with broken inversion symmetry, offering a junction free pathway for self‐powered optoelectronic devices and conceptually overcoming the Shockley‐Queisser efficiency limit of conventional ju...

Crystallographic Orientation Controls Contact and Spin-Photoresponse in 2D Magnetic Heterostructures

Abstract Two-dimensional ferromagnetic semiconductors such as CrSBr offer exceptional air stability, strong magnetic anisotropy, and rich magneto-optoelectronic coupling, yet inefficient electrical contacts continue to limit carrier injection and spin transport in practical devic...

Boosting Representation Learning for High-Level Semantic Information in Facial Expression Recognition

Facial expression recognition (FER) requires high-level semantic cues to interpret abstract emotions. However, existing FER approaches commonly suffer from sparse semantic descriptions and unwanted noise from redundant facial pixels. To tackle these issues, we propose a boosting...

Lightweight All‐Solid‐State Pouch Cells Freed from High Stack Pressure

Since 2011, ionic conductivity of some sulfide- and halide-based solid-state electrolytes (SSEs) have already reached a level comparable to that of liquid electrolytes. Numerous companies worldwide have proposed diverse technical pathways for commercializing electric vehicles wit...
