A new superconducting open-framework allotrope of silicon at ambient pressure
Ha-Jun Sung, W. H. Han, In-Ho Lee +1
Diamond Si is a semiconductor with an indirect band gap that is the basis of modern semiconductor technology. Although many metastable forms of Si were observed using diamond anvil…
Semimetallic carbon allotrope with topological nodal line in mixed - bonding networks
Ha-Jun Sung, Sunghyun Kim, In-Ho Lee +1
Graphene is known as a two-dimensional Dirac semimetal, in which electron states are described by the Dirac equation of relativistic quantum mechanics. Three-dimensional analogues…
Understanding topological phase transition in transition metal dichalcogenides
Duk-Hyun Choe, Ha-Jun Sung, Kee Joo Chang
Despite considerable interest in layered transition metal dichalcogenides (TMDs), such as MX2 with M = (Mo, W) and X = (S, Se, Te), the physical origin of their topological nature…
Localization and One-Parameter Scaling in Hydrogenated Graphene
Junhyeok Bang, K. J. Chang
We report a metal-insulator transition in disordered graphene with low coverages of hydrogen atoms. Hydrogen interacting with graphene creates short-range disorder and localizes st…
Towards unified understanding of conductance of stretched monatomic contacts
H. -W. Lee, H. -S. Sim, D. -H. Kim +1
When monatomic contacts are stretched, their conductance behaves in qualitatively different ways depending on their constituent atomic elements. Under a single assumption of resona…
