Atomic-scale mechanisms of defect- and light-induced oxidation and degradation of InSe
Andrey A. Kistanov, Yongqing Cai, Kun Zhou +2
Layered indium selenide (InSe), a new two-dimensional (2D) material with a hexagonal structure and semiconducting characteristic, is gaining increasing attention owing to its intri…
Mechanical Twinning in Phosphorene
V. Sorkin, Y. Q. Cai, D. J. Srolovitz +1
We investigate the deformation and failure mechanisms of phosphorene sheet and nanoribbons under uniaxial tensile strain along the zigzag direction using the density functional tig…
Large valley splitting in monolayer WS by proximity coupling to an insulating antiferromagnetic substrate
Lei Xu, Ming Yang, Lei Shen +3
Lifting the valley degeneracy is an efficient way to achieve valley polarization for further valleytronics operations. In this work, we demonstrate that a large valley splitting ca…
Tunable magnetization relaxation of Fe_{2}Cr_{1-x}Co_{x}Si half-metallic Heusler alloys by band structure engineering
Shikun He, Yifan Liu, Yuhong Zheng +8
We report a systematic investigation on the magnetization relaxation properties of iron-based half-metallic Heusler alloy FeCrCo_Si (FCCS) thin films using broad…
La interstitial defect-induced insulator-metal transition in oxide heterostructures LaAlO3/SrTiO3
Jun Zhou, Ming Yang, Yuan Ping Feng +1
Perovskite oxide interfaces have attracted tremendous research interest for their fundamental physics and promising all-oxide electronics applications. Here, based on first-princip…
Varying temperature and silicon content in nanodiamond growth: effects on silicon-vacancy centers
Sumin Choi, Victor Leong, Valery A. Davydov +4
Nanodiamonds containing color centers open up many applications in quantum information processing, metrology, and quantum sensing. In particular, silicon vacancy (SiV) centers are…
