We report on the 2D charge transport behavior observed in PbTeBi superlattice films. The logarithmic behavior with temperature and magnetic field was observed for the samples having the thickness of the PbTe layers larger than 45 A. This 2D behavior disappeared with annealing and, eventually, the sample showed a 3D nature for the fully annealed case.
