Abstract
The surface dislocation analysis of the three‐dimensional distortion associated with a prismatic square dislocation loop in a two‐phase medium is presented. Closed‐form expressions for the stresses and displacements due to the dislocation loop are obtained. These results are used to calculate the image force acting on the dislocation loop either due to a free surface or a second phase with a different shear modulus and Poisson’s ratio. Further, the application of the results to the formation of denuded zones free from dislocation loops in ion‐implanted silicon upon thermal annealing are illustrated in terms of the glide movement due to the attractive image force exerted by the free surface.This publication has 11 references indexed in Scilit:
