Abstract: 

THE COMPETITION BETWEEN THE RADIATIVE AND NONRADIATIVE RECOMBINATION PROCESSESHAS BEEN STUDIED BY MEANS OF THE TEMPERATURE DEPENDENCE OF THE TIME RESOLVED PHOTOLUMINESCENCE (TRPL). THE FIRST SAMPLE IS AN UNDOPED GAN/ALGAN MULTIPLE QUANTUM WELLS AND THE SECOND ONE IS A SI MODULATION-DOPED ONE WITH 9´1019CM-3 DOPING LEVEL. IT HAS BEEN DETERMINED THAT THE RADIATIVE RECOMBINATION (RR) MECHANISM DOMINATES AT THE LOW TEMPERATURE RANGE AND WITH INCREASING TEMPERATURE THE NONRADIATIVE RECOMBINATION (NRR) WILL DOMINATE. THE RESULTS DEMONSTRATE THAT THE RADIATIVE RECOMBINATION CHANNEL IS STRONGER IN THE SI DOPED SAMPLE, COMPARED TO THE UNDOPED ONE.
