Revealing Light-Magnetism Coupling via Anomalous Hall Effect and Magneto-Photoresponse in Proximity-Coupled CrSBr/Graphene Heterostructures.

The interplay between light and magnetism sparks groundbreaking concepts for the next-generation versatile spintronic and nanoelectronic devices. However, direct measurements of light-magnetism coupling remain challenging due to the intrinsic difficulties in characterizing these properties simultaneously. Herein, via harnessing magnetic proximity and anomalous Hall effect (AHE), we report the effective modification of magnetism in the graphene/CrSBr heterostructure by an unpolarized 405 nm light.

Revealing Strong Flexoelectricity and Optoelectronic Coupling in 2D Ferroelectric CuInPS Via Large Strain Gradient.

The interplay between flexoelectric and optoelectronic characteristics provides a paradigm for studying emerging phenomena in various 2D materials. However, an effective way to induce a large and tunable strain gradient in 2D devices remains to be exploited. Herein, we propose a strategy to induce large flexoelectric effect in 2D ferroelectric CuInPS by constructing a 1D-2D mixed-dimensional heterostructure.
