Abstract

The features of α-SiC (0001) epitaxially grown on top of β-SiC(l11)/Si(111) is reported by means of transmission electron microscopy (TEM). Hexagonal and rhombohedral polytype nuclei, mainly 4H-SiC, appear after the growth of a fixed cubic SiC thickness which is related to the selected growth conditions: Si/C ratio and growth temperature. The defect structure of these multilayer systems (voids, planar defects, facets and polycrystalline top clusters) and the hexagonality of the SiC surface are determined and described.
