The “Buffer” Layer in the Cvd Growth of β-SiC on (001) Silicon

Abstract
The concept of a “buffer” layer in the epitaxial growth of compound semiconductors on (001) silicon substrate is discussed on the basis of homogeneous and heterogeneous surface nucleation. Experimental results on the nucleation of β-SiC on (001) Si by Chemical Vapor Deposition (CVD) are presented and they are discussed in terms of the model for the growth of the buffer layer.
