Abstract

The systematic measurements of the hydrostatic pressure dependence of optical transitions in individual single walled carbon nanotubes (SWNTs) was investigated. The deformation potentials of nanotube band gaps were derived with an elastic model. The pressure coefficients for different nnaotube structures was expressed as the summation of a diameter-dependent term and a chiral angle-dependent term. The tight binding calculations based on graphene π-electron model showed that the band gap of a radically deformed SWNT increase or decrease on relative shift of the Fermi wave vector.
