Diamond was grown on single crystal beryllium oxide by hot-filament chemical vapor deposition. Individual diamond crystals grew epitaxially on the basal plane of BeO with the epitaxial relationship 111diamond 0001 and 1 1 0 diamond rotated by less than 6 deg from 1150 BeO. Electronic structure calculations of mixed crystals of c-BN and diamond show pronounced band gap bowing. The calculations predict only very limited mutual solubility in the solid state.
