This paper discusses the theoretical and experimental results obtained for the excitonic binding energy (E b ) in a set of single and coupled double quantum wells (SQWs and CDQWs) of GaAs/AlGaAs with different Al concentrations (Al%) and inter-well barrier thicknesses. To obtain the theoretical E b the method proposed by Mathieu, Lefebvre and Christol (MLC) was used, which is based...
