Abstract Large-density functional theory (DFT) databases are a treasure trove of energies, forces, and stresses that can be used to train machine-learned interatomic potentials for atomistic modeling. Herein, we employ structural relaxations from the

In this study, we explore the rejuvenation of a Zener diode degraded by high electrical stress, leading to a leftward shift, and broadening of the Zener breakdown voltage knee, alongside a 57% reduction in forward current. We employed a non-thermal a

Tunable plasmonic materials capable of surviving harsh environments are critical for advanced applications. Here, the authors report that some high-entropy transition-metal carbides can satisfy the requirements.

In this work, we demonstrate the rejuvenation of Ti/4H-SiC Schottky barrier diodes after forward current-induced degradation, at room temperature and in a few seconds, by exploiting the physics of high-energy electron interactions with defects. The d

Ultra-high temperature ceramics (UHTCs) present great opportunities for hypersonic applications, but densification via conventional sintering is challenging and often requires sintering aids, limiting UHT applications. Field-assisted sintering techno
