Large Plate CdTe Synthesis by Sealed Vessel Transport

Abstract

The second quarterly report for the program to grow large plates of CdTe by vapor transport in a sealed system covers the period May-June, 1982. Altogether 14 attempts have been made to compound CdTe and then transport the material into a separate plate chamber. Plates 6'' in diameter have been formed only twice. Progress has been hampered by quartz failure believed due to attack by cadmium vapor. Failure to transfer is believed to be due to deviation from stoichiometry and plugging of the transfer tube between the two chambers. A process change planned for next quarter should eliminate these problems.
