Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

Advanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Effect of Annealing Temperature on the Structural, Morphological, and Optical Properties of CdSeTe Nanoparticles for Optoelectronic Applications

Advanced Physics Research, EarlyView.
A correlation between thermal treatment and enhanced crystalline quality, surface morphology, and optical response. As annealing temperature increases, structural refinement (evidenced by phrase transition from hexagonal to cubic), and more defined morphology (seen via SEM), and improved optical absorption and bandgap tuning (UV–vis and PL spectra) are

An Advanced Epitaxial Strategy Enabling Vertical GaN Devices on Silicon Wafers

Advanced Physics Research, EarlyView.
A universal epitaxial strategy overcomes the long‐standing limitation of insulating buffers in GaN‐on‐Silicon technology. By exploiting a unique amorphous‐like interlayer (AL‐IL) formed via ultrathin metal pre‐deposition, high‐quality GaN films with excellent vertical conductivity are realized on silicon wafers.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.
