Abstract
Electron energy relaxation in the asymmetric double quantum dot system is calculated numerically using the material parameters of GaAs. The double dot consists of two tunneling coupled quantum dots each having a single nondegenerate electronic orbital. The effect of the intradot multiple scattering of the electron on the longitudinal optical phonons is considered. The inter-dot interaction is provided by the electronic tunneling mechanism. The dependence of the relaxation rate on the thickness of the tunneling barrier and on the temperature is calculated.
