Parameters for the calculation of the resistivity and Hall coefficient for the double-layered samples. Shorthand notations for the parameters of the initial PbTe film and the double-layered structure of porous PbTe layer on top of the unmodified PbTe film after anodic electrochemical treatment for the analysis of the resistivity and Hall coefficient change during pore formation. dinit, initial thickness; ρinit, resistivity of the initial lead telluride films; RH init, initial layer Hall coefficient; dpor, thickness of the porous layer; ρpor, resistivity of the porous layer; RH por, porous layer Hall coefficient; dun, thickness of the underlying layer.
