Semimetallic conductivity was observed in PbTe/PbS SL obtained by a "hot wall" technique on (001) KCl substrates with (001) PbTe buffer layers. From the analysis of R_{H}(H) and p_{⊥}(H) dependencies by the Monte-Carlo fitting procedure the band offset ΔE_{v} = 0.32 ± 0.05 eV was obtained (T = 77 K) and it was proved that these SLs are type II "misaligned" structures. The calculations of the band structure of PbTe/PbS SLs showed that in such SLs a semimetal-semiconductor transition should occur for layer thicknesses of about 60÷70 Å.
