| Description | Continuum simulations of the self-organized, lateral compositional modulated growth of nearly lattice-matched semiconductor superlattices are presented. The results of the simulations are compared to the results of synchrotron x-ray diffraction experiments of InAs/AlAs superlattices. We find that the time evolution of the compositional modulation during epitaxial growth can be explained by including a nonlinear dependence of the elastic energy of the growing epitaxial layer onits thickness. From the fit of the experimental data to the growth simulations the parameters of this nonlinear dependence are determined. |
