The first interface study of an MBE-grown GaInAs/GaAsSb heterostructure lattice-matched to InP has been performed by Auger electron spectroscopy combined with ion sputtering. No surface segregation of Sb in the GaInAs/GaAsSb heterostructure was observed. The measured interface width of this heterostructure was found to be 2.2 nm by monitoring the Auger peak-to-peak height of the Sb MNN transition under 0.5 kV Ar+ ion sputtering
