Edge-functionalization of armchair graphene nanoribbons with pentagonal-hexagonal edge structures
Junga Ryou, Jinwoo Park, Gunn Kim +1
Using density functional theory calculations, we have studied the edge-functionalization of armchair graphene nanoribbons (AGNRs) with pentagonal-hexagonal edge structures. While t…
Equilibrium structures of water molecules confined within a multiply connected carbon nanotube: a molecular dynamics study
Taehoon Kim, Gwan Woo Kim, Hyunah Jeong +2
Water confinement inside a carbon nanotube (CNT) has been one of the most exciting subjects of both experimental and theoretical interest. Most of the previous studies, however, co…
Zero-line modes at stacking faulted domain walls in multilayer graphene
Changhee Lee, Gunn Kim, Jeil Jung +1
Rhombohedral multilayer graphene is a physical realization of the chiral two-dimensional electron gas that can host zero-line modes (ZLMs), also known as kink states, when the loca…
Is hexagonal boron nitride always good as a substrate for carbon nanotube-based devices?
Seoung-Hun Kang, Gunn Kim, Young-Kyun Kwon
Hexagonal boron nitride sheets have been noted especially for their enhanced properties as substrates for sp2 carbon-based nanodevices. To evaluate whether such enhanced properties…
Interlayer coupling enhancement in graphene/hexagonal boron nitride heterostructures by intercalated defects and vacancies
Sohee Park, Changwon Park, Gunn Kim
Among two-dimensional atomic crystals, hexagonal boron nitride (hBN) is one of the most remarkable materials to fabricate heterostructures revealing unusual properties. We perform…
Decay behavior of localized states at reconstructed armchair graphene edges
Changwon Park, Jisoon Ihm, Gunn Kim
Density functional theory calculations are used to investigate the electronic structures of localized states at reconstructed armchair graphene edges. We consider graphene nanoribb…
