Radiative recombination mechanism in GaNxP1-x alloys
2002 (English)In: Applied Physics Letters, ISSN 0003-6951, Vol. 80, 1740- p.Article in journal (Refereed) Published
Based on the results of temperature-dependent photoluminescence (PL) and absorption measurements, the PL emission in GaNP epilayers and GaNP/GaP multiple quantum well structures with N composition up to 4% is shown to be dominated by optical transitions within deep states likely related to N clusters. With increasing N composition, these states are shown to become resonant with conduction band of the alloy and thus optically inactive, leading to the apparent redshift of the PL maximum position.
