Phosphorene and Transition Metal Dichalcogenide 2D Heterojunctions: Application in Excitonic Solar Cells
Vellayappan Dheivanayagam S/O Ganesan, Chun Zhang, Yuan Ping Feng +1
Using the first-principles GW-Bethe-Salpeter equation method, here we study the excited-state properties, including quasi-particle band structures and optical spectra, of phosphore…
Band gap engineering in graphene and hexagonal BN antidot lattices: A first principles study
Aihua Zhang, Hao Fatt Teoh, Zhenxiang Dai +2
Effects of antidot lattices on electronic structures of graphene and hexagonal BN (h-BN) are investigated using the first principles method based on density functional theory. For…
Dielectric properties and lattice dynamics of alpha-PbO2-type TiO2: The role of soft phonon modes in pressure-induced phase transition to baddeleyite-type TiO2
Yongqing Cai, Chun Zhang, Yuan Ping Feng
Dielectric tensor and lattice dynamics of alpha-PbO2-type TiO2 have been investigated using the density functional perturbation theory, with a focus on responses of the vibrational…
Strain effects on work functions of pristine and potassium-decorated carbon nanotubes
Yongqing Cai, Aihua Zhang, Yuan Ping Feng +3
Strain dependence of electronic structures and work functions of both pristine and potassium doped (5,5) (armchair) and (9,0) (zigzag) carbon nanotubes (CNTs) has been thoroughly s…
Graphene-based spintronic components
Minggang Zeng, Lei Shen, Haibin Su +3
A major challenge of spintronics is in generating, controlling and detecting spin-polarized current. Manipulation of spin-polarized current, in particular, is difficult. We demonst…
