Resumo

Long-wavelength acoustic phonon-assisted relaxation rates for the excited 1s(T), 2p0, 2s, 3p0, 2p±, 4p0, and 3p± states of antimony donors in a germanium crystal are calculated. The effect of the uniaxial compressive strain of a crystal along the [111] crystallographic direction on the relaxation rates is discussed. The results of calculations are compared with the measured times of relaxation of nonequilibrium states of donor centers by the pump-probe method. A comparison with the times obtained experimentally by the submillimeter photoconductivity method is made.
