Carbon Containing Platelets in Silicon and Oriented Diamond Growth

We analyse be means of transmision electron microscopy techniques the processes during the initial stages of diamond growth by magnetron sputtering. We show that a comparatively high density of C is found as deep as 100 nm in the Si substrate. The carbon arranges in planar defects in {111} and in {001} lattice planes. Our analysis shows that these defects can best be described by coherently strained inclusions that resemble hexagonal SiC platelets. These can act as seeds for orientated growth of diamond on Si.

Keywords: carbon, platelets, diamond
