Quantum kinetic theory of phonon-assisted carrier transitions in nitride-based quantum-dot systems
Abstract.
A microscopic theory for the interaction of carriers with LO phonons
is used to study the ultrafast carrier dynamics in nitride-based
semiconductor quantum dots. It is shown that the efficiency of
scattering processes is directly linked to quasi-particle
renormalizations. The electronic states of the interacting system are
strongly modified by the combined influence of quantum confinement and
polar coupling. Inherent electrostatic fields, typical for InGaN/GaN
quantum dots, do not limit the fast scattering channels.
