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…
Exploring the Charge Localization and Band Gap Opening of Borophene: A First-Principles Study
Andrey A. Kistanov, Yongqing Cai, Kun Zhou +3
Recently synthesized two-dimensional (2D) boron, borophene, exhibits a novel metallic behavior rooted in the s-p orbital hybridization, distinctively different from other 2D materi…
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…
Graphene helicoid as novel nanospring
Haifei Zhan, Yingyan Zhang, Chunhui Yang +2
Advancement of nanotechnology has greatly accelerated the miniaturization of mechanical or electronic devices. This work proposes a new nanoscale spring - a graphene nanoribbon-bas…
The Best Features of Diamond Nanothread for Nanofiber Application
Haifei Zhan, Gang Zhang, Vincent B. C. Tan +1
Carbon fibers, especially those constructed from carbon nanotubes (CNTs), have attracted intensive interests from both scientific and engineering communities due to their outstandi…
Origin of Contact Resistance at Ferromagnetic Metal-Graphene Interfaces
Khoong Hong Khoo, Wei Sun Leong, John T. L. Thong +1
Edge contact geometries are thought to yield ultralow contact resistances in most non-ferromagnetic metal-graphene interfaces owing to their large metal-graphene coupling strengths…
