GaNAs/GaAs triple quantum wells (QWs) grown by chemical beam epitaxy are annealed by two methods, ex situ rapid thermal annealing (RTA) and in situ annealing in a growth chamber followed by ex situ RTA (NRTA). The effects of annealing method on the structural, morphological, and optical properties of the QWs are studied comparatively. The results show that although there is surface desorption for both RTA and NRTA, the holes on the sample surface after desorption are clearly different. RTA is better than NRTA from the viewpoints of both surface morphology and optical properties.
