Dl. Patrick et Tp. Beebe, ON THE ORIGIN OF LARGE-SCALE PERIODICITIES OBSERVED DURING SCANNING-TUNNELING-MICROSCOPY STUDIES OF HIGHLY ORDERED PYROLYTIC-GRAPHITE, Surface science, 297(3), 1993, pp. 120000119-120000121
Scanning tunneling microscopy was used to investigate the origin of a
large-scale periodicity observed on the basal plane of highly ordered
pyrolytic graphite. Similar phenomena have previously been ascribed to
a rotational misorientation between the uppermost graphite layers. We
report the first direct measurement of graphite interlayer rotational
alignment in the presence of a superlattice, and find that misorienta
tion is not the cause.
