PbTe films, undoped and doped with 0.02,0.3 mol% Cr and 0.02 mol% Co, grown by pulsed-laser evaporation (PLE) on different types of substrates have been investigated. The crystal structure of the films was studied by X-ray diffraction. Along with the stable fcc phase, metastable GeS-and CsCI-type ph
## Abstract The MBE growth of PbTe layers on GaAs (100) 2Β° offβoriented substrates belongs to hard heteroepitaxy, because the two materials differ strongly in their lattice constants and, in addition, they also exhibit different crystal structures. Consequently, phases with different surface orient
