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…
Band gap control of small bundles of carbon nanotubes using applied electric fields: A density functional theory study
Gunn Kim, J. Bernholc, Young-Kyun Kwon
Electrostatic screening between carbon nanotubes (CNTs) in a small CNT bundle leads to a switching behavior induced by electric field perpendicular to the bundle axis. Using a firs…
Tunable charge donation and spin polarization of metal adsorbates on graphene using applied electric field
Jae-Hyeon Parq, Jaejun Yu, Young-Kyun Kwon +1
Metal atoms on graphene, when ionized, can act as a point charge impurity to probe a charge response of graphene with the Dirac cone band structure. To understand the microscopic p…
