Schematic diagram showing deformation of the crystal structure of polished graphite. a Original graphite structure prior to sample preparation. b Graphite structure after cutting by a diamond-tipped saw. The surface condition is disturbed, and cleavages developed within the graphite sheets. c Graphite sheets are peeled by shearing during polishing, and a gap is formed between them. The kink is formed by bending of the graphite sheet. The peeled graphite sheet further peels off, and fragments of the sheet fill the gap. d The final crystal structure of graphite is disturbed by polishing. Fractures are concentrated near the polished surface
