There are random oriented hexagon network of graphite (002 plane) on the surface of isotropic graphite. The random oriented structure of 002 planes are quite different from sapphire substrate. We expect to get interesting and distinctive GaN sample, use isotropic graphite as substrate for GaN growth.
GaN crystal growth were confirmed by XRD and PL. We will show rocking curves along 002 plane and other analyses of GaN on isotropic graphite, and discuss the feature of the sample.
