The goal of this MURI was to advance the technology in chalcopyrite and microstructured zincblende semiconductors, and to demonstrate devices based on them. The program involved modeling, synthesis, characterization, and device demonstration. Research was focused on, (1) nonlinear chalcopyrites and microstructured zincblende crystals for applications to mid-infrared coherent sources, and (2) magnetic chalcopyrites for future application to spintronic and magneto-optic devices. We sought to enable applications such as compact high-power ...
