Article Abstract
Using a first-principles approach, this study delves into the effects of strain and electrostatic doping on the electronic and magnetic properties of the GaN/VTevan der Waals (vdW) heterostructure. The results reveal that when the GaN/VTevdW heterostructure is doped with 0.1/0.2of electrostatic charge, its magnetization direction undergoes a remarkable reversal, shifting from out-of-plane orientation to in-plane direction. Therefore, we conduct a thorough investigation into the influence of electron orbitals on magnetic anisotropy energy. In addition, as the strain changes from -1% to 1%, the 100% spin polarization region of the GaN/VTevdW heterostructure becomes smaller. It is worth noting that at a doping concentration of 0.1, the GaN/VTevdW heterostructure has a Curie temperature of 30 K above room temperature. This comprehensive study provides valuable insights and provides a reference for analyzing the electronic and magnetic properties of low-dimensional systems.

Incorporating atomically thin two-dimensional (2D) materials with optical fibers expands their potential for optoelectronic applications. Recent advancements in chemical vapor deposition have enabled the batch production of these hybrid fibers, paving the way for practical implementation. However, their functionality remains constrained by the integration of a single 2D material, restricting their versatile performance.

Two-dimensional (2D) materials offer strong light-matter interaction and design flexibility beyond bulk semiconductors, but an intrinsic limit is the low absorption imposed by the atomic thickness. A long-sought-after goal is to achieve complementary absorption enhancement through energy transfer (ET) to break this limit. However, it is found challenging due to the competing charge transfer (CT) process and lack of resonance in exciton states.

Highly efficient optoelectronic devices of ultrasmall sizes are demanded as building blocks of next-generation integrated circuits, where tunable color enhances the feasibility of various applications. Here, we realize tunable multicolor nanolasers using disk-shaped axial heterostructures composed of III-nitride materials (GaN/InGaN/GaN), leveraging the optical confinement effect and active waveguiding. In heterostructure nanodisks, the development of exciton-polariton induces unique features near the resonance regime, and the formation of whispering-gallery modes facilitates optical gain processes for the polaritonic lasing of GaN.

Recent advancements in high-resolution spectroscopy analyses within the scanning transmission electron microscope (STEM) have paved the way for measuring the concentration of chemical species in crystalline materials at the atomic scale. However, several artifacts complicate the direct interpretation of experimental data. For instance, in the case of energy-dispersive X-ray (EDX) spectroscopy, the linear dependency of local X-ray emission on composition is disrupted by channeling effects and cross-talk during electron beam propagation.

Piezocatalytic HO generation has emerged as a promising alternative for sustainable HO synthesis, yet its development is hindered by unsatisfactory energy conversion efficiency. Herein, a TiO/ZnO piezocatalyst was developed by dispersing ZnO nanorods within a TiO nanosheet substrate, enabling efficient HO generation in pure water. By constructing a heterostructure, we developed an effective strategy to enhance charge carrier separation and migration through a built-in electric-field-induced piezoelectric effect, thereby demonstrating the superior piezocatalytic performance of the TiO/ZnO composite.
