Complementary optoelectronic effect in silicon nanomembrane-based heterojunction for broadband UV–visible–NIR photodetection
Semiconductor heterojunctions play a vital role in the fabrication of broadband photodetectors, which offer broad application prospects across fields including environmental monitoring, biomedical ima...
Spin Hall effect in DCA-based organic microcavities at room temperatre
Organic semiconductors have emerged as promising platforms for room-temperature exciton–polariton physics. However, the optical spin Hall effect (OSHE) has yet to be observed in real space within 9,10...
Regrowth-free blue GaN-based photonic crystal surface-emitting lasers with triangular air holes
We report the successful realization of a room-temperature blue GaN photonic crystal surface-emitting laser (PCSEL) diode fabricated using a regrowth-free approach. By employing a square lattice photo...
Spatially confined chloride passivation for efficient and stable green ZnSeTe quantum-dot light-emitting diodes
ZnSeTe quantum-dot light-emitting diodes (QLEDs) are attractive for cadmium-free green displays, but their performance is limited by surface-trap-assisted nonradiative recombination and interfacial in...
Magnetization reversal mechanism of double-helix nanowires probed by dark-field magneto-optical Kerr effect
Double-helix (DH) nanowires provide a platform to study the influence of geometric chirality on spin chirality. Their three-dimensional (3D) helical architecture and tunable inter-strand coupling enab...
