Abstract
The effects of misfit dislocation interaction and 90 degrees-type misfit di slocations on strain relaxation behavior in a strained layer are considered theoretically. Our results show that the interaction of misfit dislocation s is responsible for the large residual strain in the strained epilayer and that 90 degrees-type misfit dislocations play a very important role in the final stage of strain relaxation. The strain is relaxed more completely by 90 degrees misfit dislocations than by 60 degrees dislocations. The theory is consistent with experimental results. (C) 1998 Science Ltd. All rights reserved.
