Optical Properties of Short-Period InAs/GaSb Superlattices Grown by MOCVD

This paper reports the structural and photoluminescent study results of heterostructure with short-period InAs/GaSb superlattice grown by MOCVD with 8/10 ML period thickness. The photoluminescence spectra was observed in the range of 3–5 μm with intensity peak at 3.8 μm. SL minibands theoretical calculation with a high accuracy confirmed the experimental data obtained. This indicates that the specified structural parameters match the chosen growth conditions.
