The investigation of the second phase in Hg1−xCdxTe crystals
A structural defect called the second phase has been observed in Hg1−xCdxTe crystals grown by the technique of quick directional freezing. The main composition of the second phase is Te.Cd and Hg contents in the second phase are much less than that in the other part of the crystals. The second phase is caused by the improper compensation of Hg and Te in the sealed quartz ampule.
