Abstract
A comparative study of structural and superconductive properties of semiconductor epitaxial superlattices PbTe-SnTe and PbTe—PbS grown on (001) KCl has been carried out. It has been found that the superconductivity of the PbTe—SnTe superlattices is caused by the stretching strain in the SnTe layers and it may be connected with the relative positions of L+8 and terms of PbTe and SnTe, respectively in the heterojunction. In contrast to the PbTe—SnTe superlattices, the superconductivity of the PbTe—PbS superlattices is found to be associated with regular misfit dislocation grids which are generated at the interfaces.
