ZYA_DS
Technical specification
HOPG ZYA Quality - Mosaic Spread: 0.3-0.5 degree
HOPG piece has a top working layer with mosaic spread 0.3-0.5 degree and a base layer (about 1mm) with not specified mosaic spread quality. To mark the non-working HOPG piece side the one-side scotch is used.
To clean and smooth the graphite sample, do the following:
a. Stick a piece of the adhesive tape (slightly wider than the sample) on the surface of the graphite sample.
b. Smooth it out to remove air bubbles.
c. With an abrupt movement remove the adhesive tape together with the top layer of graphite. The molecular layers of graphite have a spalling angle in relation to the surface layer, at which the layers are easily removed. Therefore the smoothness of the surface will depend on the direction, in which you remove a layer. Find the best direction to obtain the smoothest surface and remember (or mark) it, to use it later for cleaning the surface of pyrolitic graphite samples.
