Study of temperature dependence of electron-phonon relaxation and dephasing in semiconductor double-dot nanostructures

This paper examines mechanisms of relaxation and dephasing of electrons in double-dot nanostructures due to interaction with acoustic phonon modes. The effect of temperature of phonon bath on decay on electron quantum evolution is obtained. Our results set the temperature ranges outside of which the...

Description
Summary:This paper examines mechanisms of relaxation and dephasing of electrons in double-dot nanostructures due to interaction with acoustic phonon modes. The effect of temperature of phonon bath on decay on electron quantum evolution is obtained. Our results set the temperature ranges outside of which the quantum dynamics of electrons will be significantly suppressed.
