Abstract
We report the observation of interband exciton transitions in InSb/Alx In1-xSb multi-quantum-well samples. The exciton peaks are identified w ith the use of a simple quantum well model. The strain present in the InSb wells alters the spectrum significantly from that for unstrained III-V materials and makes it possible to use the exciton spectrum in d etermining the band offset.
