Abstract

We report on the mechanism of electronic structure and different carrier relaxation processes in InAs/InxGa1-xAs dots-in-a-well (DWELL) structure investigated by comprehensive spectroscopic characterization. Selectively excited photoluminescence and photoluminescence excitation analyses reveal that when excited at different photon energies, carriers relax to the ground state of the quantum dots by distinct schemes. Our investigation clearly manifests the roles of longitudinal optical phonons and absorption continuum states played in the carrier relaxation process in DWELL structures.
