Characterization of nanoblisters on HOPG surface

, 2019
We report on influence of the surface functionalization on the properties of highly oriented pyrolytic graphite. The samples were processed in nitric acid and characterized by XPS, Raman and EDX spectroscopies, AFM, SEM and optical microscopy.

Cantilever flexure, adhesive/attractive and lateral force measurements on highly-oriented pyrolytic graphite by scanning force microscopy

, 1998
Pre-existing defects in the surface of highly-oriented pyrolytic graphite (HOPG) can be etched out by reaction with oxygen at high temperature. The result of this treatment is a population of one-monolayer-deep etch pits on the surface. An etch pit edge,
