POLYCRYSTALLINE HEXAGONAL BORON NITRIDE FILMS ON SIO[SUB]2 FOR III-V SEMICONDUCTOR APPLICATIONS
1989
Isotropic hexagonal BN (h-BN) films were deposited on SiO/sub 2/ crucibles used for synthesis of GaAs. Deposited films were analyzed for composition, morphology, and growth rates using proton resonant scattering, optical absorption, x-ray and electron diffraction, and transmission electron microscopy. The silicon concentration of GaAs synthesized in BN coated crucibles was approximately one order of magnitude higher than that for GaAs synthesized in uncoated crucibles under identical synthesis conditions.
