5. purity: >99.99%
Advantages of Highly Oriented Pyrolytic Graphite（HOPG）:
1. The most prominent feature is a very smooth surface and conductivity. HOPG has a layered structure that makes sample preparation very simple. Press a double-sided adhesive on the HOPG and peel off to get a new smooth, electrically conductive surface..
1.HOPG can be used for surface roughness measurement, surface microscopic properties characterization, etc.This is because the HOPG surface is almost a graphite layer, and the standard high-directional regular hexahedral atomic arrangement makes the surface roughness less than 0.1nm.
