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…
Pseudospin rotation and valley mixing in electron scattering at graphene edges
Changwon Park, Heejun Yang, Andrew J. Mayne +5
In graphene, the pseudospin and the valley flavor arise as new types of quantum degrees of freedom due to the honeycomb lattice comprising two sublattices (A and B) and two inequiv…
Dissociation of ssDNA - Single-Walled Carbon Nanotube Hybrids by Watson-Crick Base Pairing
Seungwon Jung, Misun Cha, Jiyong Park +5
The unwrapping event of ssDNA from the SWNT during the Watson-Crick base paring is investigated through electrical and optical methods, and binding energy calculations. While the s…
Controlling Half-Metallicity of Graphene Nanoribbons by Using a Ferroelectric Polymer
Yea-Lee Lee, Seungchul Kim, Changwon Park +2
On the basis of first-principles computational approaches, we present a new method to drive zigzag graphene nanoribons (ZGNRs) into the half-metallic state using a ferroelectric ma…
