Scanning tunneling microscopy of various graphitic surfaces (original) (raw)

This paper presents a study of various graphitic surfaces, including highly oriented pyrolytic graphite (HOPG), pyrolytic graphite (PG), benzene-derived graphite (BDG), and triphenylene-derived graphite (TDG), using scanning tunneling microscopy (STM). The research highlights significant features such as crystallite sizes, surface symmetry, and the presence of hexagonal etch pits resulting from oxidation processes. Additionally, the findings illustrate the effectiveness of STM in providing detailed insights into the surface characteristics of graphitic materials.
