Fundamental Study of Defects and Their Reduction in Type-II Superlattice Materials

Arizona State University (Zhang, Smith, and Johnson) will provide MBE grown samples and microstructural characterization studies of these samples. The work will include the growth, passivation, and in-situ monitoring of defects in novel type-II super lattice structures, the characterization and modeling of defects, the fundamental chemistry and physics of material and interface defects, and the impact of defects on the device physics of near, mid, and long wave infrared detectors and emitters.
