A new 2D auxetic CN2 nanostructure with high energy density and mechanical strength
Qun Wei, Ying Yang, Alexander Gavrilov +1
The existence of a new two dimensional CN2 structure was predicted using ab-initio molecular dynamics (AIMD) and density-functional theory calculations. It consists tetragonal and…
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…
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…
Quantum confinement and edge effects on electronic properties of zigzag green phosphorene nanoribbons
Chi Ma, Tianxing Ma, Xihong Peng
First principles density-functional theory calculations were performed to investigate quantum confinement and edge effects on the electronic properties of zigzag green phosphorene…
