Abstract
A resistivity minimum, with a log T dependence, has been observed in a single crystal of Pb0.99Ge0.01Te. This behaviour is interpreted in terms of scattering from double potential wells which represent the alternative positions of the Ge2+ ions below the structural phase transition. Specific heat measurements on the same sample show a low-temperature anomaly consistent with this interpretation.Keywords
