- We analyse properties of thin SnTe layers and PbTe/SnTe heterostructures grown by MBE on BaF$\text{}_{2}$(111) substrates. Reflection high energy electron diffraction patterns registered during MBE growth of the samples as well as post-growth X-ray diffraction measurements evidence a high structural perfection of 0.6 μm thick SnTe layers and (50 Å PbTe)/(50 Å SnTe) superlattices. The full width at half maximum values of (222) X-ray rocking curves measured for these thin SnTe layers crystallized in the optimal MBE growth conditions are about 300 arcsec; the carrier concentrations can be tuned from 5×10$\text{}^{19}$ cm$\text{}^{-3}$ to 10$\text{}^{2 1}$ cm$\text{}^{-3}$ depending on the MBE process parameters.
