What is Percolation effects in semimetallic Bi‐Sb solid solutions about?

## Abstract The dependences of the microhardness, electrical conductivity, the Hall coefficient, charge carrier mobility, magnetoresistance, and the Seebeck coefficient on Sb concentration (0–2 at.%) for Bi‐Sb solid solutions were obtained in the temperature range 77–300 K. It was established that the concentration dependences of the properties exhibit a non‐monotonic behavior. The existence of the peculiarities in the concentration curves is attributed to critical phenomena accompanying the transition of percolation type from an impurity discontinuum to an impurity continuum in Bi–Sb solid solutions. It was shown that the behavior of the curves is similar for cast and pressed samples and is independent of the annealing time. The results obtained in this work represent another evidence for our proposition about the universal character of critical phenomena that occur in solid solutions under the transition to an impurity continuum.
