Polaron ground state in a double heterostructure of polar crystals
Abstract
The ground-state energy and effective mass of a polaron in the GaAs well of a GaAs/AlAs double heterostructure are calculated as functions of the well width. In considering electron-phonon interactions, both the confined LO were included as well as the interface phonon modes. The results differ qualitatively from what can be found in the literature, demonstrating the importance of interface modes as well as the confinement of LO modes.
