Research Abstract

We proposed crystal growth using seed crystals with controlled configuration as a new method to form twin supperlattice in a bulk Si crystal. We found that tilt deviation from the twin configuration and change in the growth rate are important factor in the twin formation. Reduction in dislocation density around the twins is an issue in the future.
