Research Abstract

A surface modification and lateral growth were applied to reduce the dislocation in the SiC grown layers. When a SiC layer was grown on the surface modified substrate, the basal plane dislocations were converted to the threading dislocations. The dislocation density in SiC could be reduced at the lateral growth area.
