Paper Title:
High SiC Growth Rate Obtained by Vapour-Liquid-Solid Mechanism
  Abstract

The growth of 3C-SiC polycrystal and 6H-SiC homoepitaxial layers from Metal-Si alloys is carried out as function of temperature and propane partial pressure. Based on the vapourliquid- solid mechanism, we present a new configuration for the growth of SiC which could allow first to simplify the liquid handling at high temperature and second to precisely control the crystal growth front. 3C-SiC crystals exhibiting well-faceted morphology are obtained at 1100-1200°C with outstanding deposition rates, varying from 1 to 1.5 mm/h in Ti-Si melt. At 1200-1300°C, thick homoepitaxial 6H-SiC layers were successfully obtained in Co-Si melts, with growth rates up to 200 ,m/h. Details on the experiments will be given and the potentialities of such process for the growth of bulk crystals will be discussed..
