Characterization of DNA-Carbon Nanotube Hybrids by their van Hove Singularities
نویسندگان
چکیده
The optical dichroism which appears in the nanotube–DNA hybrid is studied within a phenomenological approach. Naturally non–chiral nanotubes may acquire a chiral optical response when wrapped by the DNA helix. The hybrids of the DNA and the metallic nanotubes are discussed in conjunction with the possible gap opening and the subsequent arising of a pair of van Hove singularities close to the Fermi point. Polarized light absorption experiments are proposed to find the predicted effect.

The optical resonances in carbon nanotubes arise from excitons.
Optical transitions in carbon nanotubes are of central importance for nanotube characterization. They also provide insight into the nature of excited states in these one-dimensional systems. Recent work suggests that light absorption produces strongly correlated electron-hole states in the form of excitons. However, it has been difficult to rule out a simpler model in which resonances arise fro...
متن کاملElectronic Density of States of Atomically Resolved Single-Walled Carbon Nanotubes: Van Hove Singularities and End States
The electronic densities of states of atomically resolved single-walled carbon nanotubes have been investigated using scanning tunneling microscopy. Peaks in the density of states due to the one-dimensional nanotube band structure have been characterized and compared with tight-binding calculations. In addition, tunneling spectroscopy measurements recorded along the axis of an atomically resolv...
متن کاملTime-domain ab initio simulation of electron and hole relaxation dynamics in a single-wall semiconducting carbon nanotube.
The electron and hole relaxation in the (7, 0) zigzag carbon nanotube is simulated in time domain using a surface-hopping Kohn-Sham density functional theory. Following a photoexcitation between the second van Hove singularities, the electrons and holes decay to the Fermi level on characteristic subpicosecond time scales. Surprisingly, despite a lower density of states, the electrons relax fast...
متن کاملOptical characterization of DNA-wrapped carbon nanotube hybrids
Optical characterization of DNA-wrapped CoMoCAT carbon nanotube hybrids (DNA–CNT) and semiconductor-enriched DNA–CNT was carried out using resonant Raman spectroscopy (RRS) and photoluminescence (PL) experiments. The values of radial breathing modes frequency xRBM were found to be relatively insensitive to the type of wrapping agents surrounding the nanotube. The values of xRBM and the first an...
متن کاملOptical Switching of Single-Wall Carbon Nanotube Absorption Through Field Gating
Semiconducting single-wall carbon nanotubes have an absorption band centered about approximately 0.7 eV. This arises from the transition between the first valence band Van Hove singularity and the first conduction band singularity in the density of states. These singularities lie close enough to the Fermi-level that it is possible to shift the Fermi-level sufficiently to exclude this electronic...
