Morphological instability of GaInNAs quantum wells on AlGaAs/GaAs distributed bragg reflectors grown by metal-organic vapor-phase epitaxy
2002 (English)In: Conference Proceedings - International Conference on Indium Phosphide and Related Materials, Stockholm, 2002, 241-244 p.Conference paper, Published paper (Refereed)
Abstract [en]

We report on the optical and structural integrity of metal-organic vapor-phase epitaxy grown GaInNAs/GaAs single quantum wells on AlGaAs/GaAs distributed Bragg reflectors (DBRs). Surface morphology as measured by atomic force microscopy and quantum well photoluminescence were investigated for different numbers of DBR periods and different DBR-growth temperatures. Increased number of DBR periods severely degrades the surface morphology and photoluminescence. However, a significant improvement was obtained by lowering the growth temperature of the DBRs from 745 to 680°C.
