Atomic scale electronic structure of the ferromagnetic semiconductor Cr2Ge2Te6
Zhenqi Hao, Haiwei Li, Shunhong Zhang +6
Cr2Ge2Te6 is an intrinsic ferromagnetic semiconductor with van der Waals type layered structure, thus represents a promising material for novel electronic and spintronic devices. H…
The role of interstitial hydrogen in SrCoO antiferromagnetic insulator
Li Liang, Shuang Qiao, Shunhong Zhang +2
Hydrogen exhibits qualitatively different charge states depending on the host material, as nicely explained by the state-of-the-art impurity-state calculation. Motivated by a recen…
π-Conjugation in Epitaxial Si(111)-() Surface: an Unconventional "Bamboo Hat" Bonding Geometry for Si
Wei Jiang, Zheng Liu, Miao Zhou +2
The newly observed () surface reconstruction in heteroepitaxial Si(111) thin films on metal substrates is widely considered as a promising platform to reali…
Selective doping Barlowite for quantum spin liquid: a first-principles study
Zheng Liu, Xiaolong Zou, Jia-Wei Mei +1
Barlowite is a newly found mineral containing kagome planes. Despite similarities in many aspects to Herbertsmithite , the well-known qu…
Structural, electronic, and magnetic properties of tris(8-hydroxyquinoline)iron(III) molecules and its magnetic coupling with ferromagnetic surface: first-principles study
Wei Jiang, Miao Zhou, Zheng Liu +3
Using first-principles calculations, we have systematically investigated the structural, electronic, and magnetic properties of facial (fac-) and meridional (mer-) tris(8-hydroxyqu…
Epitaxial growth of large-gap quantum spin Hall insulator on semiconductor surface
Miao Zhou, Wenmei Ming, Zheng Liu +3
Formation of topological quantum phase on conventional semiconductor surface is of both scientific and technological interest. Here, we demonstrate epitaxial growth of 2D topologic…
sd2 Graphene: Kagome Band in Hexagonal lattice
Miao Zhou, Zheng Liu, Wenmei Ming +2
Graphene, made of sp2 hybridized carbon, is characterized with a Dirac band, representative of its underlying 2D hexagonal lattice. Fundamental understanding of graphene has recent…
Organic Topological Insulators in Organometallic Lattices
Z. F. Wang, Zheng Liu, Feng Liu
Topological insulators (TIs) are a recently discovered class of materials having insulating bulk electronic states but conducting boundary states distinguished by nontrivial topolo…
Electronic Strengthening of Graphene by Charge Doping
Chen Si, Wenhui Duan, Zheng Liu +1
Graphene is known as the strongest 2D material in nature, yet we show that moderate charge doping of either electrons or holes can further enhance its ideal strength by up to ~17%,…
Flat Chern Band in a Two-Dimensional Organometallic Framework
Zheng Liu, Zheng-Fei Wang, Jia-Wei Mei +2
By combining exotic band dispersion with nontrivial band topology, an interesting type of band structure, namely the flat chern band (FCB), has recently been proposed to spawn high…
Stable nontrivial Z2 topology in ultrathin Bi (111) films: a first-principles study
Zheng Liu, Chao-Xing Liu, Yong-Shi Wu +3
Recently, there have been intense efforts in searching for new topological insulator (TI) materials. Based on first-principles calculations, we find that all the ultrathin Bi (111)…
