Abstract

The reactions between misfit dislocations arriving by glide at the interface between an In0.12Ga0.88As/GaAs multilayer and a GaAs substrate are analysed and reported. The glide forces for the (a/2)<110> dislocations are calculated as a function of vicinal tilt from (001) to (100). It is observed that the 4% changes in the magnitude of the force for a 2° vicinal angle are not sufficient to significantly alter the relative linear densities of the different types of dislocation.
