•Very similar to ZYB grade which exhibits a mosaic angle as small as 0.8 +/- 0.2 degree. •The HOPG has a structure of polycrystals, the size of which varies, the max. being 10 mm for the highest quality. The fres •The lateral grain size can be up to 0.5 mm but can be as large as 1 mm.

Surface fitness
As Cleaved
Surface roughness
< 80.9 Angstrom RMS and the freshly cleaved surface consists of atomic steps, 0.2 - 0.3 nm and steps of several or dozens of atomic layers.
The higher the quality, the less the roughness of the surface and the samller the number of such steps on a freshly cleaved surface.
