Abstract

The electronic structure changes of single wall carbon nanotube (SWCNT) bundles under compression were studied. The examination of electronic band structure revealed that bundles of SWCNTs with three-fold symmetry increased the quasi band gaps, while bundles of SWCNTs without three-fold symmetry remained metallic under hydrostatic compression. It was found that the opposing hexagons between graphene layers were unfavourable and led to structural instability and increased metallic features in the electronic bands.
