Nano-indentation at temperatures up to 600 degrees C has been applied to the (0001) surface of highly oriented pyrolytic graphite using a spherical diamond tip (similar to 10 mu m diameter). Cross-sectional observations of the indentations by dark field scanning transmission electron microscopy show an increased tendency at high temperature for inelastic deformation by buckling of the graphite crystals with kink formation.
