Abstract:

During this reporting period, Na-doping work continued, and, in addition, work began with P- and Sb-doping. The laboratories also began to use a new 6N super high-purity Se source material obtained from Osaka Asahi, with consequent marked improvement in unintentionally-doped material quality. As evident from this report, extrinsic donor impurities from the source materials may be responsible for the difficulties encountered in obtaining p-ZnSe. Efforts in double crystal x-ray rocking curve DCRC and transmission electron microscopy studies, as well as e beam and optical pumping, and Schottky and ohmic contact work are continuing. Keywords Blue Green Lasers.
