New Mechanism for Strongly Bound Excitons in Gapless Two-Dimensional Structures
Yufeng Liang, Ryan Soklaski, Shouting Huang +4
Common wisdom asserts that bound excitons cannot form in high-dimensional (d>1) metallic structures because of their overwhelming screening and unavoidable resonance with nearby co…
Quasiparticle band-edge energy and band offsets of monolayer of molybdenum and tungsten chalcogenide
Yufeng Liang, Shouting Huang, Ryan Soklaski +1
We report the quasiparticle energy of monolayer of molybdenum and tungsten dichalcogenides, MX2 (M=Mo, W; X=S, Se, Te). Beyond calculating bandgaps, we have achieved converged abso…
Exciton Energy Spectra in Two-Dimensional Graphene Derivatives
Shouting Huang, Yufeng Liang, Li Yang
The energy spectra and wavefunctions of bound excitons in important two-dimensional (2D) graphene derivatives, i.e., graphyne and graphane, are found to be strongly modified by qua…
Electronic Structure and Quasiparticle Band Gap of Silicene Structures
Shouting Huang, Wei Kang, Li Yang
We report first-principles results on the electronic structure of various silicene structures. For planar and simply buckled silicenes, we confirm their zero-gap nature and show a…
Lattice Vibrational Modes in Si/Ge Core-shell Nanowires
Shouting Huang, Li Yang
We present a first-principles study on lattice vibrational modes of Si/Ge core-shell nanowires (NWs). In addition to quantum confinement, the internal strain induced by the lattice…
Many-Electron Effects on Optical Absorption Spectra of Strained Graphene
Yufeng Liang, Shouting Huang, Li Yang
We employ the first-principles GW+Bethe Salpeter equation approach to study the electronic structure and optical absorption spectra of uniaxial strained graphene with many-electron…
