Abstract
The control of dislocation density during the growth of GaAs and related compounds is highly desirable for obtaining improved performance and reliability of opto-electronic devices. Doping of single crystal GaAs grown by the LEC process with Indium has been known to reduce the dislocation density significantly. Substitutional solid-solution strengthening of GaAs as an InAs unit been suggested to be responsible for reduction of dislocation density. To understand the mechanism involved in dislocation density reduction deformation tests have been performed on [001] oriented Ga_XIn_(1-x)As single crystals in the temperature range 700-1100°C and this paper reports some results of the TEM characterization of dislocations in these deformed single crystals.
