New stable two dimensional silicon carbide nanosheets
Qun Wei, Ying Yang, Guang Yang +1
We predict the existence of new two dimensional silicon carbide nanostructure employing ab initio density-functional theory calculations. These structures are composed of tetragona…
New stable crystal structures of C and GeC2 predicted from first-principles calculations
Ying Yang, Guang Yang, Xihong Peng
Two novel three-dimensional (3D) crystal structures of carbon (C) and germanium carbide (GeC2) were predicted using first-principles density-functional theory (DFT) calculations. T…
Enhanced carrier mobility in anisotropic 2D tetrahex-carbon through strain engineering
Xihong Peng, Qun Wei, Guang Yang
A recently predicted two dimensional (2D) carbon allotrope, tetrahex-carbon consisting of tetragonal and hexagonal rings, draws research interests due to its unique mechanical and…
Valley polarization and valleyresistance in monolayer transition metal dichalcogenides superlattice
Hui-Ying Mu, Yi-Tong Yao, Jie-Ru Li +7
Manipulating the valley degree of freedom to encode information for potential valleytronic devices has ignited a new direction in solid-state physics. A significant, fundamental ch…
Auxetic tetrahex-carbon with ultrahigh strength and direct band gap
Qun Wei, Guang Yang, Xihong Peng
Tetrahex-carbon is a recently predicted two dimensional (2D) carbon allotrope which is composed of tetragonal and hexagonal rings. Unlike flat graphene, this new 2D carbon structur…
Superior mechanical flexibility and strained-engineered direct-indirect band gap transition of green phosphorene
Guang Yang, Tianxing Ma, Xihong Peng
Most recently, a brand new phosphorus allotrope called green phosphorus has been predicted, which has a direct band gap up to 2.4 eV, and its single-layer form termed green phospho…
