"Raman spectroscopy of single-wall carbon nanotube"

December 11, 2007

12:00 noon - 1:00 p.m. Grier Room 34-401


Abstract:

A single wall carbon nanotube (SWNT) is a new form of carbon, whose atomic arrangement is equivalent to a graphene sheet rolled into a cylinder in a seamless way. Due to its small diameter and high aspect ratio, a SWNT has very unique electronic and vibrational properties. A widerly-tunable micro Raman instrument with diffraction efficiencies exceeding 90% is developed for studying various properties of SWNTs. Results from the study of the electronic transition energies, diameter, length, substrate interaction, and strain level are presented.
