Topology related changes in the local density of states near the ends of closed carbon nanotubes are investigated using spatially resolved scanning tunneling spectroscopy and tight binding calculations. Sharp resonant valence band states are observed in the experiment at the tube ends, dominating the valence band edge and filling the band gap. Calculations show that the strength and position of these states with respect to the Fermi level depend sensitively on the relative positions of pentagons and their degree of confinement at the tube ends.read more

Electronic structure of atomically resolved carbon nanotubes
TL;DR: In this paper, the results of scanning tunnelling microscopy and spectroscopy on individual single-walled nanotubes from which atomically resolved images allow us to examine electronic properties as afunction of tube diameter and wrapping angle.

Atomic structure and electronic properties of single-walled carbon nanotubes
TL;DR: In this paper, the structure and electronic properties of single-walled carbon nanotubes (SWNTs) were investigated using tunnelling microscopy, and it was shown that the SWNT samples exhibit many different structures, with no one species dominating.

Carbon nanotube quantum resistors
TL;DR: The conductance of multiwalled carbon nanotubes (MWNTs) was found to be quantized and Extremely high stable current densities, J > 10(7) amperes per square centimeter, have been attained.

Electrostatic deflections and electromechanical resonances of carbon nanotubes
TL;DR: The methods developed here have been applied to a nanobalance for nanoscopic particles and also to a Kelvin probe based on nanotubes, which indicates a crossover from a uniform elastic mode to an elastic mode that involves wavelike distortions in the nanotube.
