摘要: In this article, we report on scanning tunneling microscopy (STM) observations of several different kinds superlattice boundaries highly-oriented pyrolytic graphite (HOPG) including an array bead-like structures, a monolayer deep trench, zig-zag shaped termination, and plain boundary without features. Results simulation model show that top rotated layer with straight does not necessarily lead to the resulting as has been previously claimed. The formation bead-like, is explained from energetic point view. Our study also shows evidence for superlattice-mediated observation low-angle grain varying tilt angle. A relationship between periodicity dislocations across derived. result work important understanding superlattices whose origin yet completely understood.
