Superconductivity of Non-Strained PbTe-PbS and Strained PbTe-SnTe Superlattices

Year: 1991

Type: article

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.
