DFT Modeling and Impedance Spectroscopy Analysis of a High Performance Zirconia‐Based Solar Cell

Nano Select, EarlyView.
p‐SnS/n‐CdS heterojunction solar cells with Al‐ZnO/i‐ZnO window layers simulated using SCAPS‐1D and impedance spectroscopy enabled tracking of solar cell parameters. The optimal performance (η = 22.76%, Voc = 0.77 V) was achieved with a 5 µm SnS absorber at Rs = 1Ω.cm−2 and Rsh = 10 kΩ.cm−2.

Epitaxy and Phase Stability of 2D Hexagonal Gallium Telluride on Silicon

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Two‐stage amorphization as a function of annealing temperature of continuous, strain‐free, high‐crystalline‐quality 2D hexagonal gallium telluride on silicon obtained by van der Waals epitaxy. Controlling crystal quality during epitaxial growth is essential for the advancement of novel materials with industrial relevance.

Substitutional Sulfur and Its Vibrational Fingerprints in Sb2Se3

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The microscopic configurations of sulfur incorporated into the Sb2$_2$Se3$_3$ lattice are studied by combining infrared absorption spectroscopy with density functional theory. Substitutional SSe$_{\mathrm{Se}}$ defects are identified as the origin of four distinct sulfur‐related local vibrational modes at 249, 273, 283, and 312 cm−1$^{-1}$.

Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2

Advanced Quantum Technologies, EarlyView.
Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage

Rare Metals, EarlyView.
ABSTRACT Tungsten disulfide (WS2) is considered a promising anode material for sodium‐ion batteries (SIBs). However, its practical application is hindered by poor electrical conductivity, large volume changes during cycling, and sluggish ion diffusion kinetics, which lead to unsatisfactory electrochemical performance.
