Abstract: | The theory of exciton polaron in quantum well is developed. The interaction with symmetric interface phonons is shown to contribute significantly to polaron exciton binding energy. As a result, this energy depends both on effective masses of charge particles in the quantum well and on polarization properties of the barriers. The conditions are found for strong exciton–phonon coupling in quantum well. |
