摘要：
An analysis of a misfit dislocation array in a Ga0.85In0.15As/GaAs superlattice on GaAs has been performed on a microscopic scale. The Burgers vectors of the misfit dislocations present were determined using plan-view transmission electron microscopy (TEM). This data has been used in a recent formulation of the Frank-Bilby equation to obtain the deformation of the layer. The state of strain is compared with the Matthews model of strain relief, and the layer is found to be metastable; only 45% of the strain energy of the layer has been relieved in comparison with an equilibrium value of 81%.
