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…
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…
Analysis of the near-resonant fluorescence spectra of a single rubidium atom localized in a three-dimensional optical lattice
Wookrae Kim, Changwon Park, Jung-Ryul Kim +3
Supplementary information is presented on the recent work by W. Kim et al. on the matter-wave-tunneling-induced broadening in the near-resonant spectra of a single rubidium atom lo…
Spontaneous edge-defect formation and defect-induced conductance suppression in graphene nanoribbons
Jia Li, Zuanyi Li, Gang Zhou +5
We present a first-principles study of the migration and recombination of edge defects (carbon adatom and/or vacancy) and their influence on electrical conductance in zigzag graphe…
Releasing H2 molecules with a partial pressure difference without the use of temperature
Hoonkyung Lee, Bing Huang, Wenhui Duan +1
Using the pseudopotential density functional method as well as equilibrium thermodynamic functions, we explore the process of releasing H2 molecules adsorbed on a transition metal…
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…
