On the intracenter relaxation of shallow antimony donors in strained germanium
V. V. Tsyplenkov, V. N. Shastin Institute for Physics of Microstructures, Russian Academy of Sciences, Nizhnii Novgorod
Abstract:
Long-wavelength acoustic phonon-assisted relaxation rates for the excited $1s(T)$, $2p_{0}$, $2s$, $3p_{0}$, $2p_\pm$, $4p_{0}$, and $3p_\pm$ 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.
Keywords:
germanium, shallow donors, relaxation, radiation of phonons.
