Bond Distortions in Armchair Type Single Wall Carbon Nanotubes

N. Sunel, E. Rizaoglu, K. Harigaya +1

The energy band gap structure and stability of (3,3) and (10,10) nanotubes have been comparatively investigated in the frameworks of the traditional form of the Su-Schrieffer-Heege…

STM observation of electronic wave interference effect in finite-sized graphite with dislocation-network structures

Yousuke Kobayashi, Kazuyuki Takai, Ken-ichi Fukui +4

Superperiodic patterns near a step edge were observed by STM on several-layer-thick graphite sheets on a highly oriented pyrolitic graphite substrate, where a dislocation network i…

STM observation of the quantum interference effect in finite-sized graphite

Yousuke Kobayashi, Kazuyuki Takai, Ken-ichi Fukui +4

Superperiodic patterns were observed by STM on two kinds of finite-sized graphene sheets. One is nanographene sheets inclined from a highly oriented pyrolitic graphite (HOPG) subst…
