R-plane sapphire can be used in a variety of applications, including growing Silicon on Sapphire (SOS). R-plane SoS chips work great radiation hardware, from integrated circuits to photovoltaics.

R-plane sapphire has a small, energetically unrelaxed geometry over all four surface facets. A comparison of sapphire c and m planes in the spheres shows that there is no significant difference in the energy distribution between the two planes on the surface layer. There are no differences in surface energy between the c - r plane and the o-final layer of a GaN template.
