Novel superconducting superlattices, having transition temperature ranging from 2.5 to 6.4K, were identified which consisted only of semiconducting materials. Among these were multi-layers which included a wide-gap semiconductor as one of the components. It was shown that superconductivity was connected with the interfaces between 2 semiconductors that contained regular grids of misfit dislocations. The possibility of dislocation-induced superconductivity was considered.
