摘要：

The decay time of the linear polarization degree of the luminescence in strongly confined semiconductor quantum dots with asymmetrical shape is calculated in the frame of second-order quasielastic interaction between quantum dot charge carriers and LO phonons. The phonon bottleneck does not prevent significantly the relaxation processes and the calculated decay times can be of the order of a few tens picoseconds at temperature Tsimilar or equal to100 K, consistent with recent experiments by Paillard [Phys. Rev. Lett. 86, 1634 (2001)].
