Interface Phonon Influences on Formation of Polaron States in Quantum Nanostructures

Abstract

In the present work the theory of polaron states in the quantum wells, quantum wires and quantum dots is developed with due regard for the interaction of charge particles both with bulk and with interface optical phonons. The polaron binding energies are obtained. For the quantum dot case, the contributions of bulk and interface phonons have commensurable quantities. The interface phonon role is much more important in the quantum wells and wires. The essential strengthening as well as the attenuation of polaron interaction is possible with the different interrelations of the structure and the barrier dielectric properties.
