Abstract

In this paper we report, the effects of strain on the electronic properties of single wall carbon nanotubes and its consequence on the resonant Hainan cross section. A quantum interference effect has been predicted for the radial breathing mode spectra for metallic tubes. For metallic tubes, the lower and upper components of Eii resulting from the trigonal warping effect are affected differently and for low chiral angle they cross for some strain value. Near (at) the crossing point, the resonant Raman spectra profile exhibits a maximum (minimum) value due to a quantum interference in the Hainan cross section, This Raman cross section interference effect was observed in Raman experiments carried out on isolated SWNTs, The Raman experiment performed on an isolated strained metallic SWNT supports our modeling predictions.
