摘要：
A microscopic theory is applied to study carrier-carrier Coulomb scattering in nitride-based quantum dots. Kinetic equations for the carrier population are used to define capture and relaxation rates. For the states involved in the scattering processes, the combined influence of the quantum-confined Stark effect and many-body renormalizations is taken into account. It is shown that the charge separation due to the built-in field is accompanied with strong Hartree energy shifts, which can increase the scattering efficiency. (c) 2006 WILEY-VCH Verlag GmbH & Co.
