Abstract

We investigated the rapid enlargement of SiC single crystal during physical vapor transport growth by enhancing the lateral growth. The degrees of enlargement of the single crystals grown on the newly developed graphite lid were larger than those of crystals grown on the conventional one. Using a cone-shaped platform, the polycrystals grown around the single crystal could assist the lateral growth of single crystal. There was no significant difference between the central region and the enlarged region as far as the micropipe density was considered. The dependence of the broadening angle (β) of the single crystal on the taper angle (θ) of the cone-shaped platform was also investigated and an optimum angle at a given growth condition was found.
