Shape control and emission wavelength extension of InP-based InAsSb nanostructures

Lei, Wen; Jagadish, Chennupati; Tan, Hark Hoe


This paper presents a study on the shape control and emission wavelength extension of InP-based InAsSb nanostructures. InGaAs buffer layer, combined with low growth temperature and medium V/III ratio, provides an effective approach to fabricate InAsSb QDs. By using InGaAsSb sandwich layer to serve as both strain reducing layer and metamorphic buffer layer, the emission wavelength of InAsSb QDs can be extended well beyond 2 μm, which is very useful for their application as mid-infrared emitters.
