The zinc oxide is a promising material for the realization of optoelectronic devices in the blue-UV range. For this, it is necessary to develop hetero-structures such as ZnO / (Zn, Mg) O quantum wells in order to have better control of the properties of emissions. This work concerns the characterization of such structures grown on the A-plane (non-polar surface) of bulk ZnO. From optical spectroscopies measurements (reflectivity, continuous wave and time-resolved photoluminescence) we determined the various physical phenomena involve during the radiative recombination of the carriers in these quantum wells. At first, we studied in detail the emission of photons by the barriers of (Zn, Mg) O. Thanks to the study in temperature we showed that...
