Giant bulk photovoltaic effect driven by interfacial symmetry breaking in MoS2/Ta2NiSe5 heterostructures

Van der Waals (vdW) heterostructures offer a versatile platform for engineering unconventional bulk photovoltaic (BPV) effect through interfacial symmetry breaking. However, the coexistence of multiple photophysical mechanisms, driven by structural complexity, spontaneous charge...

Long-Range Synchronization of Remote NV Color-Center Ensembles via an Active Microwave Cavity

For scalable quantum networks and distributed quantum sensing, remote NV color-center spin ensembles require controllable long-range coherent connections. However, the magnetic dipole coupling between NV centers decays rapidly with distance, making direct stable coherent exchange...

Space-ConfinedGrowth of 2D Ultrathin Ternary CdZnTeFlakes toward High-Performance Photodetectors

Abstract Two-dimensional (2D) CdZnTe has been highly anticipated in high-performance photodetectors because of its excellent optoelectronic properties and the quantum confinement effect in 2D scale. However, due to the intrinsically nonlayered structure, the current obtained 2D C...

A look at nanowire photodetectors

Nanowire (NW) photodetectors have emerged as a prominent group of optoelectronic materials that have been extensively researched over the last two decades. They belong to the one-dimensional nanostructures and operate in the regime of wave optics because the diameter of the NW is...

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...

Breathing ferroelectricity, flat-bands and multiple chiral phonons in van der Waals breathing kagome Nb3Cl8

Van der Waals layered Nb3X8 (X=Cl, Br, I) are predicted to integrate multiple intriguing physical properties, notably multiferroicity and flat-bands that are highly promising for novel-principle memories and superconductors. However, direct experimental validations such as the pr...

CDGP-Net: Channel-Decoupling and Geographic-Prior Fusion for Spatial Super-Resolution of HIRAS Radiances with Co-Platform MERSI-II

Hyperspectral infrared sounders provide valuable observations for numerical weather prediction (NWP), but their native nadir spatial resolution of approximately 12–16 km is coarser than the approximately 4 km grid spacing commonly used in convection-permitting regional forecastin...

An engineered metal-to-insulator transition in a two-dimensional network of degenerate phosphorus quantum dots in silicon

Phosphorus quantum dots (QDs) in silicon are a prominent candidate for semiconductor quantum computing based on donor spins. In this work, we report the formation of degenerate phosphorus QDs with a radius of 3 nm confined in a two-dimensional plane in silicon. A multilayer of Si...
