Edge state on hydrogen-terminated graphite edges investigated by scanning tunneling microscopy

Yousuke Kobayashi, Ken-ichi Fukui, Toshiaki Enoki +1

The edge states that emerge at hydrogen-terminated zigzag edges embedded in dominant armchair edges of graphite are carefully investigated by ultrahigh-vacuum scanning tunneling mi…

Observation of zigzag and armchair edges of graphite using scanning tunneling microscopy and spectroscopy

Yousuke Kobayashi, Ken-ichi Fukui, Toshiaki Enoki +2

The presence of structure-dependent edge states of graphite is revealed by both ambient- and ultra-highvacuum- (UHV) scanning tunneling microscopy (STM) / scanning tunneling spectr…

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…

Theoretical study on novel electronic properties in nanographite materials

Kikuo Harigaya, Atsushi Yamashiro, Yukihiro Shimoi +8

Antiferromagnetism in stacked nanographite is investigated with using the Hubbard-type model. We find that the open shell electronic structure can be an origin of the decreasing ma…

Novel electronic wave interference patterns in nanographene sheets

Kikuo Harigaya, Yousuke Kobayashi, Kazuyuki Takai +2

Superperiodic patterns with a long distance in a nanographene sheet observed by STM are discussed in terms of the interference of electronic wave functions. The period and the ampl…
