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…
