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…
Reversible Metal-Semiconductor Transition of ssDNA-Decorated Single-Walled Carbon Nanotubes
Misun Cha, Seungwon Jung, Moon-Hyun Cha +3
A field effect transistor (FET) measurement of a SWNT shows a transition from a metallic one to a p-type semiconductor after helical wrapping of DNA. Water is found to be critical…
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…
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…
First-principles study of ultrathin (2 \times 2) Gd nanowires encapsulated in carbon nanotubes
Jae-Hyeon Parq, Jaejun Yu, Gunn Kim
Using density functional calculations, we investigate the structural and magnetic properties of ultrathin Gd and Gd-carbide nanowires (NWs) encapsulated in narrow carbon nanotubes…
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…
