Abstract
This invention is directed to a method for shifting the mosaic spread of highly oriented pyrolytic graphite ("HOPG") into a preselected narrow range. The method involves selecting HOPG samples having a mosaic spread which lies below a desired mosaic spread range and cold working the selected samples to form a textured surface sufficent to shift the mosaic spread of the samples into the desired mosaic spread range. The textured surface is preferably imprinted by pressing the samples between metal dies with at least one of the dies having a knurled surface.
