Metastable states and their resonant electron-phonon interaction of hydrogen-like donors in GaAs
The FTIR photoconductivity measurements and theoretical comparison of the magnetic field induced metastable states of the hydrogen-like donors in GaAs are reported in this paper. The transitions from the ground bound Is state to the high-lying metastable states of Si donors are observed and identified. A simplified trial wave-function is applied to these high-lying metastable states and the variational calculations are in good agreement with our experimental data. The electron-phonon interaction related with the metastable states are investigated. Integrated energy spectra consist of the resonant magneto-polaron branches and the bound phonon branches, which corresponding to the multiple phonon process, are obtained for the first time.
