Quantum spin Hall effect in two-dimensional transition-metal chalcogenides
Xing Wang, Wenhui Wan, Yanfeng Ge +2
Based on first-principles calculations, we have found a family of 2D transition-metal (TM) chalcogenides MX5 (M = Zr, Hf and X = S, Se and Te) can host quantum spin Hall (QSH) effe…
Superconductivity in graphite-diamond hybrid
Yanfeng Ge, Kun Luo, Yong Liu +8
Search for new high-temperature superconductors and insight into their superconducting mechanism are of fundamental importance in condensed matter physics. The discovery of near-ro…
Electronic Transport of Two-Dimensional Ultrawide Bandgap Material h-BeO
Yanfeng Ge, Wenhui Wan, Yulu Ren +2
Two-dimensional ultrawide bandgap materials, with bandgaps significantly wider than 3.4 eV, have compelling potential advantages in nano high-power semiconductor, deep-ultraviolet…
Single Pair of Charge-two Weyl Fermions in Chiral Boron Allotropes
Hui-Jing Zheng, Yan Gao, Yanfeng Ge +2
The realization of a minimal Weyl semimetal (WSM) hosting a single pair of Weyl points (WPs) has thus far been restricted to magnetic systems, since time-reversal symmetry generall…
Hole-Doped Room-Temperature Superconductivity in HSZ (Z=C, Si)
Yanfeng Ge, Fan Zhang, Ranga P. Dias +2
We examine the effects of the low-level substitution of S atoms by C and Si atoms on the superconductivity of HS with the structure at megabar pressure. The hole d…
Diverse magnetism in stable and metastable structures of CrTe
Na Kang, Wenhui Wan, Yanfeng Ge +1
In this paper, we systematically investigated the structural and magnetic properties of CrTe by combining particle swarm optimization algorithm and first-principles calculations. W…
