Abstract: 

THE COMPETITION BETWEEN THE PHOTO-GENERATED CARRIERS AND THE SI DOPING LEVEL ON THE SCREENING OF THE INTERNAL POLARIZATION FIELDS IN MODULATION-DOPED GAN/AL0.07GA0.93N MULTIPLE-QUANTUM-WELL (MQW) STRUCTURES WERE STUDIED BY MEANS OF PHOTOLUMINESCENCE (PL) AND TIME-RESOLVED PL MEASUREMENTS. UNDOPED AND LOW-DOPED SAMPLES INDICATE A QW EMISSION, WHICH IS RED SHIFTED BY A FEW MEV DURING THE FIRST 600 PS IN TIME DELAYED SPECTRA DUE TO THE SCREENING OF THE INTERNAL POLARIZATION FIELDS, BUT THERE IS ALMOST NO SHIFT FOR THE MEDIUM AND HIGH DOPED SAMPLES BECAUSE OF THE COMPETITION BETWEEN THE PHOTO-GENERATED CARRIERS AND SI DOPING LEVEL IS DOMINATED BY THE EXTRINSIC CARRIERS IN THE MEDIUM AND HIGH DOPED SAMPLES.
