Pressure-induced superconductivity in topological type II Dirac semimetal NiTe2
Tao Li, Ke Wang, Chunqiang Xu +10
Very recently, NiTe2 has been reported to be a type II Dirac semimetal with Dirac nodes near the Fermi surface. Furthermore, it is unveiled that NiTe2 presents the Hall Effect, whi…
Emergence of Type-I and Type-II Dirac line nodes in penta-octa-graphene
Heng Gao, Wei Ren
Carbon allotropes have a large family of materials with varieties of crystal structures and properties and can realize different topological phases. Using first principles calculat…
Mesoscopic Electronic Transport in Twisted Bilayer Graphene
Yulei Han, Yafei Ren, Xinlong Dong +3
We numerically investigate the electronic transport properties between two mesoscopic graphene disks with a twist by employing the density functional theory coupled with non-equili…
Insulator-metal transition and quasi-flat-band of Shastry-Sutherland lattice
Huai-Xiang Huang, Jing Chen, Wei Ren +3
Insulator-metal transition is investigated self-consistently on the frustrated Shastry-Sutherland lattice in the framework of Slave-Boson mean-field theory. Due to the presence of…
First-principles study of the structural, electronic, magnetic and ferroelectric properties of a charge ordered Iron(II)- Iron(III) formate framework
Gang Tang, Wei Ren, Jiawang Hong +1
Density functional theory calculations have been performed for the structural, electronic, magnetic and ferroelectric properties of a mixed-valence Fe(II)-Fe(III) formate framework…
Metallic Network of Topological Domain Walls
Tao Hou, Yafei Ren, Yujie Quan +3
We study the electronic and transport properties of a network of domain walls between insulating domains with opposite valley Chern numbers. We find that the network is semi-metall…
