The effect of the different regimes of heat treatment on the kinetics of electronic processes in silicon crystals doped with phosphorus impurity via the melt and by nuclear transmutation technique. The most significant influence of cooling under intermediate value of cooling rate (ucl » 15 оС/min) after high-temperature annealing on the main electrophysical parameters of the transmutation-doped n‑Si áPñ crystals was established. Features of changes of the anisotropy parameters of mobility and thermal electromotive force measured on silicon crystals of different doping techniques both in the initial state, and after high-temperature annealing when using different cooling rates, were found and explained.
