A set of evolution equations are presented in this article. The key feature of the equations is the incorporation of dislocation interactions into the kinetic process by introducing a resistance term. The resistance to threading dislocation gliding is characterized by a hardening function, which depends only on the relaxed plastic strain. The evolution equations are tested on the GexSi1 - x/Si(100) materials system. Existing fundamental parameters are incorporated into the present model. The evolution equations successfully reproduce a wide range of experimental data on strain relaxation in GexSi1 - x/Si heterostructures. © 2001 American Institute of Physics. | Source Title: | Journal of Applied Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/82163 | ISSN: | 00218979 | DOI: | 10.1063/1.1369396 |
