Reflux annealing device and method

摘要

Methods of annealing Hg1-xCdxTe slices (56) in a mercury reflux chamber (32, 34) with a mercury reservoir (52) at the bottom and condensation regions at the top (62) is disclosed. The chamber is heated by a furnace (44) that creates an annealing region encompassing both the reservoir and a holder (46) for the Hg1-xCdxTe slices (56). In preferred embodiment methods reservoir (52) is heated to 270 DEG C. for two hours to sixty days. An annealing immediately after LPE growth by use of either mercury vapor from the melt or a separate reservoir is also disclosed.
