Origin of Symmetric Dimer Images of Si(001) Observed in Low-Temperature STM
Xiao-Yan Ren, Hyun-Jung Kim, Chun-Yao Niu +2
It has been a long-standing puzzle why buckled dimers of the Si(001) surface appeared symmetric below 20 K in scanning tunneling microscopy (STM) experiments. Although such symmetr…
Competing Magnetic Orderings and Tunable Topological States in Two-Dimensional Hexagonal Organometallic Lattices
Hyun-Jung Kim, Chaokai Li, Ji Feng +2
The exploration of topological states is of significant fundamental and practical importance in contemporary condensed matter physics, for which the extension to two-dimensional (2…
Giant Spin-Orbit-Induced Spin Splitting in Bi Chains on GaAs(110)
Hyun-Jung Kim, Jun-Hyung Cho
The search for one-dimensional electron systems with a giant Rashba-type spin splitting is of importance for the application of spin transport. Here we report, based on a first-pri…
Contrasting interedge superexchange interactions of graphene nanoribbons embedded in h-BN and graphane
Sun-Woo Kim, Hyun-Jung Kim, Jin-Ho Choi +2
Based on first-principles density-functional theory calculations, we present a comparative study of the elec- tronic structures of ultranarrow zigzag graphene nanoribbons (ZGNRs) e…
Equivalence of Electronic and Mechanical Stresses in Structural Phase Stabilization: A Case Study of Indium Wires on Si(111)
Sun-Woo Kim, Hyun-Jung Kim, Fangfei Ming +4
It was recently proposed that the stress state of a material can also be altered via electron or hole doping, a concept termed electronic stress (ES), which is different from the t…
Nature of the Insulating Ground State of the 5d PostPerovskite CaIrO3
Sun-Woo Kim, Chen Liu, Hyun-Jung Kim +4
The insulating ground state of the 5d transition metal oxide CaIrO3 has been classified as a Mott-type insulator. Based on a systematic density functional theory (DFT) study with l…
