Contrasting diffusion behaviors of O and F atoms on graphene and within bilayer graphene
Seho Yi, Hyun-Jung Kim, Jin-Ho Choi +1
The chemical modification of graphene with adatoms is of importance for nanoelectronics applications. Based on first-principles density-functional theory calculations with includin…
Comment on "Quasi-One-Dimensional Metal-Insulator Transitions in Compound Semiconductor Surfaces"
Sun-Woo Kim, Yoon-Gu Kang, Hyun-Jung Kim +1
In a recent Letter, Zhao et al. [1] reported the origin of quasi-one-dimensional metal-insulator (MI) transitions in compound semiconductor surfaces. Based on a density-functional…
Spin-orbit coupling effects on the stability of two competing structures in Pb/Si(111) and Pb/Ge(111)
Xiao-Yan Ren, Hyun-Jung Kim, Seho Yi +2
Using first-principles density-functional theory (DFT) calculations, we investigate the 4/3-monolayer structure of Pb on the Si(111) or Ge(111) surface within the two competing str…
Stacking-sequence-independent band structure and shear exfoliation of two-dimensional electride materials
Seho Yi, Jin-Ho Choi, Kimoon Lee +3
The electronic band structure of crystals is generally influenced by the periodic arrangement of their constituent atoms. Specifically, the emerging two-dimensional (2D) layered st…
Origin of the Metal-Insulator Transition of Indium Atom Wires on Si(111)
Sun-Woo Kim, Jun-Hyung Cho
As a prototypical one-dimensional electron system, self-assembled indium (In) nanowires on the Si(111) surface have been believed to drive a metal-insulator transition by a charge-…
Mott- versus Slater-type Insulating Nature of Two-Dimensional Sn Atom Lattice on SiC(0001)
Seho Yi, Hunpyo Lee, Jin-Ho Choi +1
Semiconductor surfaces with narrow surface bands provide unique playgrounds to search for Mott-insulating state. Recently, a combined experimental and theoretical study [Phys. Rev.…
