摘要：

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