Abstract

The repartition ofnonradiative recombination centers density in a quantum well has been tested by timeresolved luminescence in samples containing an InAs plane inside a 16 nm wide GaAs well in Ga7AL3As. The results show unambiguously that more non radiative centers are located near the first grown interface. The non radiative carriers lifetime () vary between 4 ns when the InAs monolayer is close to the inverted interface and 8 ns when it is near the direct one.
