Abstract

Various cleaning procedures used to prepare InP surfaces for epitaxial growth and regrowth have been investigated. They include standard surface chemical cleaning treatments, UV/ozone oxidation, (NH4) 2Sx sulfidation and in situ ECR hydrogen and oxygen plasma treatments. The quality of the various treatments is evaluated on the basis of the surface chemical composition prior to growth and from the structural and electrical properties of the corresponding epilayers.
