First-principles study of an organometallic S=1/2 kagome compound
Zheng Liu, Jia-Wei Mei, Feng Liu
Cu(1,3-benzenedicarboxylate) [Cu(1,3-bdc)] contains structurally perfect kagomé planes formed by Cu ions without the presence of diamagnetic defects. This organometallic com…
Tuning Fe Nucleation Density with Charge Doping of Graphene Substrate
Wenmei Ming, Feng Liu
We have demonstrated that the island nucleation in the initial stage of epitaxial thin film growth can be tuned by substrate surface charge doping. This charge effect was investiga…
Orbit- and Atom-Resolved Spin Textures of Intrinsic, Extrinsic and Hybridized Dirac Cone States
Lin Miao, Z. F. Wang, Meng-Yu Yao +7
Combining first-principles calculations and spin- and angle-resolved photoemission spectroscopy measurements, we identify the helical spin textures for three different Dirac cone s…
Quantum Size Effect on Dielectric Properties of Ultrathin Metallic Film: A First-Principles Study of Al(111)
Wenmei Ming, Steve Blair, Feng Liu
Quantum manifestations of various properties of metallic thin films by quantum size effect (QSE) have been studied intensively. Here, using first-principles calculations, we show q…
Effects of Li doping on H-diffusion in MgH: a first-principles study
Wenmei Ming, Zhigang Zak Fang, Feng Liu
The effects of Li doping in MgH on H-diffusion process are investigated, using first-principles calculations. We have identified two key effects: (1) The concentration of H vac…
Quasiparticle Dynamics in Reshaped Helical Dirac Cone of Topological Insulators
Lin Miao, Z. F. Wang, Wenmei Ming +14
Topological insulators (TIs) and graphene present two unique classes of materials which are characterized by spin polarized (helical) and non-polarized Dirac-cone band structures,…
Interplay between Quantum Size Effect and Strain Effect on Growth of Nanoscale Metal Thin Film
Miao Liu, Yong Han, Lin Tang +3
We develop a theoretical framework to investigate the interplay between quantum size effect (QSE) and strain effect on the stability of metal nanofilms. The QSE and strain effect a…
Angle Dependent Van Hove Singularities in Slightly Twisted Graphene Bilayer
Wei Yan, Mengxi Liu, Rui-Fen Dou +7
Recent studies show that two low-energy Van Hove singularities (VHSs) seen as two pronounced peaks in the density of states (DOS) could be induced in twisted graphene bilayer. Here…
Criticality of Vacancy-Induced Metal-Insulator Transition in Graphene
Shangduan Wu, Feng Liu
The criticality of vacancy-induced metal-insulator transition (MIT) in graphene is investigated by Kubo-Greenwood formula with tight-binding recursion method. The critical vacancy…
