        • Material: Highly Oriented Pyrolytic Graphite - HOPG SPI-2 Grade
        • 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.
        • Size: 20  x 20  x 2.0 mm & 10 x 10 x1.0 mm  & 5 x 5 x 1.0 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.
        • Density: 2.27 g.cm^-3
