β¦ Synopsis
The in-plane superlattice and the twinned domain structure were found by single crystal X-ray diffraction to be preserved after exfoliation and collapse, though the graphite planes were slightly bent. The fractional expansion due to exfoliation was comparable for single crystals and HOPG. The degree of hysteresis was less for single crystals.
