Calcium-Decorated Carbon Nanotubes for High-Capacity Hydrogen Storage
Hoonkyung Lee, Jisoon Ihm, Marvin L. Cohen +1
Using first-principles calculations, we perform a search for high-capacity hydrogen storage media based on individually dispersed calcium atoms on doped or defective carbon nanotub…
Modification of the electronic structure in a carbon nanotube with the charge dopant encapsulation
Woon Ih Choi, Jisoon Ihm, Gunn Kim
We present the first-principles study of effects of the charge dopants such as Cesium and Iodine encapsulated on the electronic structure of carbon nanotubes. An encapsulated cesiu…
Origins of anomalous electronic structures of epitaxial graphene on silicon carbide
Seungchul Kim, Jisoon Ihm, Hyoung Joon Choi +1
On the basis of first-principles calculations, we report that a novel interfacial atomic structure occurs between graphene and the surface of silicon carbide, destroying the Dirac…
Combinatorial Search for Optimal Hydrogen-Storage Nanomaterials Based on Polymers
Hoonkyung Lee, Woon Ih Choi, Jisoon Ihm
We perform an extensive combinatorial search for optimal nanostructured hydrogen storage materials among various metal-decorated polymers using first-principles density-functional…
Electrical Switching in Metallic Carbon Nanotubes
Young-Woo Son, Jisoon Ihm, Marvin L. Cohen +2
We present first-principles calculations of quantum transport which show that the resistance of metallic carbon nanotubes can be changed dramatically with homogeneous transverse el…
