Although THz emission is generally attributed to spin-to-charge conversion, the contribution and microscopic origin of orbital angular momentum remain unclear. Here, we clarify the generation pathway of optical-driven ultrafast orbital currents by engineering the spin–orbit coupling (SOC) strength of the FM layer and disentangling spin- and orbital-to-charge conversion in the NM layer. Using weak-SOC Ni80Fe20 and strong-SOC Ni combined with Pt and W—materials exhibiting opposite spin Hall but identical orbital Hall polarities—we uncover a pronounced thickness-dependent crossover from spin-dominated to orbital-dominated THz emission in Ni/W bilayers. Time-resolved THz spectroscopy reveals that the orbital contribution arises from the inverse orbital Rashba–Edelstein effect, enabled by efficient spin-to-orbital conversion within the strong-SOC ferromagnet.

The transmission electron microscopy (TEM) images and electron paramagnetic resonance spectra (EPR) indicate that the strong blue photoluminescence and CPL response originate from the generation of bromine defects. Particularly, the change in the ratio of ligands not only leads to CD inversion, but also can give rise to CPL inversion. The Ultrafast spectroscopy transient absorption (TA) spectra further show that the CPL response of chiral Cs4PbBr6 NCs originates from the spin-polarization process. The reversal of the CPL signal can be attributed to the changes of energy band structure due to conformational changes with respect to S/R-MBA (MBA = α-Methylbenzylamine) ligands in chiral perovskite NCs. It indicates that the conformational change of chiral ligands can modulate the energy band structure of chiral Cs4PbBr6 perovskite NCs with keeping the crystallographic structure constant.

However, increasing pixel density within a constant emitting footprint introduces competing optical, electrical, and thermal effects that constrain link performance. Here, we investigate parallel-connected AlGaN micro-LED arrays with controlled pixel densities by partitioning a 400 × 400 µm2 emission region into 1, 4, 16, 64, and 256 pixels. All devices exhibit comparable turn-on voltages with extremely low-leakage currents, confirming that pixel subdivision does not substantially degrade junction quality. Increasing pixel density enhances light output from 2.71 mW in the single-pixel device to 3.75 mW in the 256-pixel array, which optical simulations attribute to shortened in-plane photon propagation and enhanced sidewall-assisted extraction. Thermal behavior shows a non-monotonic dependence on pixelation, with intermediate arrays operating at lower temperatures than both structural extremes. However, increasing pixel density also raises effective capacitance and reduces the peak −3 dB bandwidth. As a result, the optimum communication performance emerges at an intermediate pixelation level, where the 16-pixel array delivers a maximum data rate of 3.07 Gbps.

However, most biomimetic visual systems are limited to two-dimensional (2D) recognition via monocular manner. In contrast, binocular visual systems could extend the recognition scope from the 2D plane to three-dimensional (3D) space. This study proposes a biomimetic binocular visual system for 3D motion recognition based on β-Ga2O3 synaptic devices to gather motion information including motion direction, state, and speed. Based on trap behaviors, the broad tunability of synaptic behavior endows β-Ga2O3 synaptic device with multiple functions including photodetector (PD), compressor and activation function generator (AFG), realizing the recognition of nineteen directions in 3D space with a high accuracy of 98.83%.

However, their practical application is limited by instability under heat, oxygen, and intense illumination. To address this critical issue of stability, we proposed a dual-layer encapsulation strategy. Firstly, InP/ZnSe/ZnS QDs are synthesized via a “one-pot” approach. Then, mZIF-8@QDs materials are prepared by embedding QDs into a mesoporous zeolite imidazolate framework (mZIF) formed after pore structure modification and surface modification. Finally, a novel vacuum-assisted deposition method is employed to uniformly polymerize polymethyl methacrylate (PMMA) on the surface of mZIF-8@QDs, thereby achieving a secondary coating and obtaining the mZIF-8@QDs@PMMA composite material. The QDs loading capacity was significantly enhanced by modification of the saturated fatty acid for mesoZIF-8. The synthesized fluorescent composite material exhibits high quantum yield, long fluorescence lifetime, good photostability and thermostability. Furthermore, this composite material is used as a color conversion layer in liquid crystal displays (LCDs).
