WebJan 15, 1990 · The c-axis resistivity (ρ c) and its temperature dependence of highly oriented pyrolytic graphite have been studied in connection with the characteristic stacking-fault structure.In order to account for the observations, the pioneering theory of Ono on the tunneling conduction through the stacking-fault planes is reformulated using the concept … Highly oriented pyrolytic graphite (HOPG) is a highly pure and ordered form of synthetic graphite. It is characterised by a low mosaic spread angle, meaning that the individual graphite crystallites are well aligned with each other. The best HOPG samples have mosaic spreads of less than 1 degree. Note that … See more The method used to produce HOPG is based on the process used to make pyrolytic graphite, but with additional tensile stress in the basal-plane direction. This produces improved alignment of the graphite crystallites … See more HOPG is used in x-ray optics as a monochromator and in scanning probe microscopy as a substrate and for magnification … See more
