Abstract : Accomplishment of researches conducted under support of contract DAALO3-89-K-0119 have been reported. Two Ph. D. degrees have been granted to two students supported by this contract. A total of six categories of studies, designated for convenience, have been performed. The first five categories of studies concern the point defects and diffusion mechanisms of elements occupying the group III sub- lattice of GaAs and/or AlAs/GaAs superlattice materials, and one category of studies concerns the group V sublattice acceptor carbon in AlAs/GaAs superlattices. With theses studies, our knowledge of point defects and diffusion mechanisms of elements occupying the group III sublattice of GaAs and/or AlAs/GaAs superlattice materials have now becoming substantially complete in the sense that interpretations of almost all experimental results are self-consistent and mutually-consistent.
