MCT layers have been grown for the first time at 250-degrees-C using DATe, DMCd and mercury. First the buffer layer CdTe grown at 365-degrees-C using DIPTe and DMCd is studied with an emphasis on the influence of the substrate orientation. Indeed the surface morphology and the crystalline quality may change dramatically as a function of the substrate orientation. Then the low temperature MOVPE growth of (Cd,Hg)Te is described: different compositions were achieved and the crystalline and electronic properties are presented.
