Features of changes in the electrophysical parameters (concentrations of charge carriers ne and their mobilities μ) in heavily doped n-Ge ⟨As⟩ single crystals, which occur as a result of the series of thermoannealings (each for 0.5 h) over a wide temperature range (540 ≤ T ≤ 900 °C), have been investigated and explained. Keywords: germanium, thermoannealing, Hall effect, charge carrier concentration, charge carrier mobility.
