摘要：
High-resolution x-ray diffraction and grazing-incidence small-angle x-ray scattering are used for the investigation of the morphology of free-standing and buried self-assembled PbSe quantum dots in PbSe/PbEuTe superlattices. The measured data are simulated by means of kinematical and semikinematical scattering theories, and linear elasticity theory. The differences in the parameters of free-standing and buried dots yield a direct evidence of structure changes of self-assembled dots during their overgrowth.
