Abstract
We present calculations of Gamma-->X-z electron transfer times in type -II GaAs-AlAs and AlGaAs-AlAs superlattices as a function of the sampl e temperature. Emission and absorption of confined and interface optic al phonons via Frohlich interaction are considered as the transfer mec hanisms. The calculated transfer times and their temperature dependenc e are in good agreement with the experimental results in the literatur e.
