摘要

The method of grazing incidence X-ray diffraction (GIXRD) is used to study the hexagonal boron nitride (h-BN) films produced by plasma-enhanced chemical vapor deposition (PECVD) from borazine and ammonia or helium mixtures. The diffraction patterns of boron nitride layers aligned vertically on the substrate are obtained for the first time. The films deposited consist of the amorphous phase and the nanocrystalline h-BN phase. The nanocrystallite sizes in the films obtained from the mixtures of borazine (B3N3H6) with both ammonia and helium increase with an increase in the synthesis temperature. Nanocrystallites are heteraxial and have a layered structure with the interplanar spacing of similar to 0.35 nm.
