Electrical transport in small bundles of single-walled carbon nanotubes: intertube interaction and effects of tube deformation
Taekyung Kim, Gunn Kim, Woon Ih Choi +2
We report a combined electronic transport and structural characterization study of small carbon nanotube bundles in field-effect transistors (FET). The atomic structures of the bun…
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…
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…
Reduction of Activation Energy Barrier of Stone-Wales Transformation in Endohedral Metallofullerenes
Woon Ih Choi, Gunn Kim, Seungwu Han +1
We examine effects of encapsulated metal atoms inside a C molecule on the activation energy barrier to the Stone-Wales transformation using {\it ab initio} calculations. The…
