Abstract

Stäng
- Strong enhancement of photoluminescence intensity from InGaAs quantum wells by incorporating nitrogen in metamorphic InGaAs buffers grown on GaAs substrates was demonstrated and investigated. The enhancement of photoluminescence intensity is found to be from both the weak strain effect and the strong lattice hardening effect, indicating blocking effect of threading dislocations due to the N incorporation. Combination of this method with a strain compensated superlattice was proved to be effective in obtaining good quality metamorphic InGaAs quantum wells.
