Interface Properties of II-VI/III-V Heterostructures
Published online by Cambridge University Press: 25 February 2011
Abstract
In situ x-ray photoelectron spectroscopy (XPS) is used to study the nature of the bonding at CdTe/InSb and ZnSe/GaAs interfaces grown by molecular beam epitaxy. A comparison of the In3d core level features from the InSb epilayer surface, a Tereacted InSb surface, very thin (a few monolayers) CdTe/InSb epilayer/epilayer heterostructures and from separately grown (In,Te) epilayers, indicate similar In bonding characteristics for the Te-reacted layer, the CdTe/InSb heterostructures and the (In,Te) epilayers. A parallel XPS study of ZnSe/GaAs interfaces leads to the conclusion that there is a general tendency for the formation of a III-VI interfacial compound when forming IIVI/ III-V junctions.
