We study the epitaxial growth mechanism of diamond films using various hetero-materials as substrates in a hot-filament chemical vapor deposition (HFCVD) chamber. The same parameters were maintained in the nucleation and growth processes of diamond films on these substrates. The experimental results showed that the dominant orientation of diamond crystals has a relation with that of substrates identified by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The preference of diamond films on non-diamond substrates is explained as heteroepitaxial growth. We think that the initial nucleation process is the key to the heteroepitaxial growth of diamond film.
