Abstract
Strong magnetic field Hall coefficient and magnetoresistivity dependencies in PbTe/PbS semimetallic SLs with periods of 12.0 divided by 100.0 nm were observed. From the analysis of these dependencies by Monte-Carlo fitting procedure the band-offset (Delta) Ev equals 0.32 plus or minus 0.05 eV was obtained (T equals 77 K) and it was proved that these SLs are type II 'misaligned structures.' The band structure calculations of PbTe/PbS SLs in the envelope wave function approximation showed that in such SLs a semimetal-semiconductor transition should occur for layer thicknesses of approximately 6.0 nm.
