摘要: Abstract Electronic properties of bucky tube modelled by a sheet helical graphite cylinder named “grahelix” have been examined based on the one-dimensional tight-binding crystal orbital method in framework Huckel approximation. It has found that there are two types grahelix depending pitch, is, one is energetically stable and semiconductive whereas other less with metallic nature.
