Vertical Ferroelectricity in Van der Waals Materials: Models and Devices
Yuwen Zhang, Chunfeng Cui, Chaoyu He +4
Ferroelectricity has a wide range of applications in functional electronics and is extremely important for the development of next-generation information storage technology, but it…
I4/mcm-Si: An Ideal Topological Nodal-Line Semimetal
Laiyuan Su, Shifang Li, Jin Li +6
Topological semimetals (TSMs) have attracted numerous attention due to their exotic physical properties and great application potentials. Silicon-based TMSs are of particularly imp…
Ground state configuration of hydrogenated Biphenylene sheet: structure, stabilities, electronic and mechanical properties from first-principles calculations
YuJie Liao, XiZhi Shi, Tao Ouyang +5
Based on first-principles calculations, the ground state configuration (Cmma-CH) of hydrogenated Biphenylene sheet (Science, 372, 852, 2021) is carefully identified from hundreds o…
New structure canditates for the experimentally synthesized heptazine-based and triazine-based two dimensional graphitic carbon nitride
Luneng zhao, Xizhi Shi, Jin Li +5
The widely used crystal structures for both heptazine-based and triazine-based two-dimensional (2D) graphitic carbon nitride (g-CN) are the flat P-6m2 configurations. Howev…
Theoretical prediction of a low-energy Stone-Wales graphene with intrinsic type-III Dirac-cone
Zhenghao Gong, XiZhi Shi, Jin Li +6
Based on first-principles method we predict a new low-energy Stone-Wales graphene SW40, which has an orthorhombic lattice with Pbam symmetry and 40 carbon atoms in its crystalline…
Direct and quasi-direct band gap silicon allotropes with remarkable stability
Chaoyu He, Jin Li, xiangyang Peng +3
In our present work, five previously proposed sp carbon crystals were suggested as silicon allotropes and their stabilities, electronic and optical properties were investigated…
