Abstract :
InGaNAs/GaN MQW structures were grown on GaN/sapphire substrates by low-pressure MOCVD. We investigated the structural and optical properties of InGaNAs MQW and correlation between As concentration and In composition using X-ray diffraction (XRD), transmission electron microscopy (TEM), secondary ion mass spectrometry (SIMS) and photoluminescence (PL) spectra.
