p-Doped SiC Growth on Diamond Substrate by VLS Transport

Article Preview

Abstract:

This work deals with the study of the Selective Epitaxial Growth (SEG) of SiC using the Vapour-Liquid-Solid (VLS) transport on diamond (100) substrate with Al-Si as the liquid phase fed by propane. Morphology, structure and doping type of the SiC deposit were determined. Polycrystalline p-doped 3C-SiC was obtained during the growth. Study of the initial step of growth showed that SiC nucleation occurs without any propane addition but just through the interaction of liquid Al-Si and diamond via a dissolution/precipitation process. This explains the random nucleation and the polycrystalline growth. Despite this, preliminary electrical measurements show encouraging results.
