Abstract:

An x-ray topographic study is made of three hexagonal SiC crystals, type 6H, of different national origin. All three crystals exhibit a high density of dislocations, many originating at the nucleation edge of the crystal and fanning out to the crystal boundaries. Burgers vectors were identified. Slip in the 1,1,-2,0 direction, characteristic of hexagonal materials, was observed. Author
