Abstract
The polaronic effects for electrons confined in one-dimensional lateral quantum wires and parabolic quantum dots are calculated taking into account both the electron–bulk-LO-phonon interaction and the electron–interface-phonon interaction. We find that the effects of the interface phonons are important and cannot be neglected in these systems. Our calculations suggest that the polaron effects on quantum dots are larger than on lateral quantum wires due to the weaker in-plane confinement in the latter.
