Liquid phase epitaxial growth of CdTe/Hg1−xCdxTe multilayers (0.3<x<0.5)

CdTe/Hg1−xCdxTe multilayers (0.3<x<0.5) were obtained for the first time by a liquid phase epitaixal (LPE) technique. The layers were grown on (111)A oriented CdTe substrates. The surface morphology of these multilayers is similar to those of HgCdTe single layers reported before. The cross diffusion at the CdTe/Hg1−xCdxTe interface has been as small as 0.3 μm for the thin CdTe epilayer. The first CdTe/HgCdTe heterojunction sensitive to ∼2.8 μm at 77 K has been demonstrated.
