Role of interface optical phonons in cooling hot carriers in GaAs-AlAs quantum wells

Abstract

The interactions of electrons and optical phonons is central to our understanding of the transport and optical properties of semiconductors. Many recent optical studies have concentrated on the early phase of the dynamics of a photoexcited electron-hole plasma, taking advantage of the newly developed femtosecond laser sources. In this contribution we study the nonequilibrium optical phonon population generated by the relaxation of hot carriers photoexcited in GaAs-AlAs quantum wells under steady-state conditions.
