摘要：

Scanning tunneling microscopic images of large scale hexagonal domainlike waves superimposed on the normal atomic corrugation have been obtained on a highly oriented pyrolytic graphite surface. This hexagonal pattern had a spacing of 44 +/- 2 angstrom, an amplitude of 3.8 +/- 0.2 angstrom, and an orientation of about 30-degrees with respect to the atomic corrugation. The appearance of this type of structure may be caused by a rotation of the topmost layer of graphite relative to its neighboring underlayers.
