摘要
We describe a method to study the structure of semiconductor autoepitaxial layers grown in the form of closed cylinders on the external side surface of hollow cylindrical single-crystal substrates. We compare the values of dislocation density in the structure of nonplanar layers obtained by single-crystal X-ray diffraction analysis (measurements of rocking curves) and by the etch pit method in the [111] plane. The results of singlecrystal X-ray diffraction analysis of nonplanar autoepitaxial silicon layers are shown to be reliable.
