Quantenkinetic description of the electron-phonon-interaction in intersubband systems — •Stefan Butscher and Andreas Knorr — Institut für theoretische Physik, Nichtlineare Optik und Quantenelektronik, Technische Universität Berlin Hardenbergstr. 36, 10623 Berlin, Germany

The effect of quantum kinetic (non-Markovian) electron-phonon for semiconductor intersubband transitions is investigated. At low temperatures and even in weakly coupled systems we find that electron phonon interaction leads to a suppression of Coulomb binding effects. Furthermore, for the case of strong electron-phonon interaction a quantum kinetic description is important even at room temperatures.
