We report on the characterization of thermally induced interdiffusion in InAs/GaAs quantum-dot superlattices with high-resolution x-ray diffraction and photoluminescence techniques. The dynamical theory is employed to simulate the measuredx-ray diffraction rocking curves of the InAs/GaAs quantum-dot...
