Spectroscopic studies of diameter dependent properties defects and defect engineering in single walled and multi walled carbon nanotubes

Abstract

Carbon nanotubes CNTs are unique one dimensional nanostructures with remarkable electronic optical mechanical and thermal properties Since its discovery in 1991 CNTs have caught widespread attention of researchers worldwide for studies of fundamental properties as well as device applications Carbon nanotubes were first thought of as perfect seamless cylindrical graphene sheets a defect free structure However with time and as more studies have been undertaken it has emerged that nanotu
