Surface morphology and nanofriction of thermally treated multilayer graphene

Correlation of surface morphology alteration in affecting the nanotribological properties of multilayer graphene (Gr) film has been rarely reported in the literature. Thus, the study determines the extent of surface morphology alteration influencing the friction of multilayer Gr film. The multilayer...
