✦ Synopsis

A microscopic approach to the carrier dynamics in semiconductor heterostructures is used to study structural dephasing and phase breaking due to carrier-carrier interactions in GaAlAs-GaAs double wells. Analysis of interband polarizations allows a quantitative account of the destruction of phase coherence and its consequences on the frequency spectrum of the THz dipole radiation emitted by the carriers.
