Abstract : Intense yellow injection electroluminescence starting at 1.35 volts has been discovered and studied in physical inversion layers of metal-semiconductor contacts between high-work-function metals and n-type ZnSe. Yellow injection electroluminescence has also been found in quasihomojunctions between n-type ZnSe and p-type ZnTe grown by a new epitaxial process. For unambiguous distinction of the various injection electroluminescence effects which can be produced in one n-type ZnSe crystal, a comparative study was undertaken which yielded a set of simple criteria. N-type ZnTe crystals were produced for the first time, and the phase diagram of ZnTe was established. Optical measurements on ZnSe-ZnTe mixed crystals were undertaken. A comprehensive theory of the luminescence centers in ZnS-ZnSe mixed crystals has been worked out, which is applicable also to other mixed crystals. Rare-earthdoped, luminescent zinc sulfide crystals were grown from the melt, and work on Re-doped films was begun. (Author)
