Abstract
Grain boundaries in high-purity silicon carbide bicrystals produced by sublimation-deposition at 2800 K were examined by high-resolution transmission electron microscope (HRTEM). Two asymmetric tilt boundaries with a rotation of 70–5° about [1100], Le. a 6H polytype boundary parallel to (0001) of one of the crystals and a 6H/15R hetero-polytype boundary were observed. Both boundaries were without an amorphous layer. The periodic arrangement of atoms in the boundaries was analyzed using the geometrical coincidence-site lattice model, while the actual atomic structure of the boundary was modeled from the HRTEM images.
