Аннотация
The results of electron microscopy studies of an epitaxial InAlAs layer on a GaAs(100) substrate are reported. It is established that there exist misfit dislocations at the interface between the materials and there are residual strains distorting the lattice in the layer. From the measurements of lattice parameters in the directions parallel and orthogonal to the growth direction away from misfit dislocations, the local nominal lattice parameter of the layer is calculated and the relative content of indium is determined.
