TEMPE, Ariz. A team of Arizona State University researchers will get support from the U.S. Department of Defense to aid development of the next generations of lasers and infrared photodetectors.
The technology is widely employed in sensing and imaging for an array of defense and commercial applications.
The work will be funded by an Army Research Office grant through the defense department's Multidisciplinary University Research Initiative (MURI) program, which supports science and engineering endeavors involving research and technology development considered vital to national interests.
ASU's Yong-Hang Zhang, David J. Smith and Shane Johnson will combine expertise in electrical engineering, materials science and physics to contribute to a project in which they will collaborate with colleagues at University of Illinois at Urbana-Champaign, the Georgia Institute of Technology and the University of North Carolina.
The entire project has been approved for a grant of $6.25 million over five years. ASU's team has been awarded $2.34 million for its part of the effort.
Zhang is a professor and Johnson is a senior research scientist in the School of Electrical, Computer and Energy Engineering, one of ASU's Ira A. Fulton Schools of Engineering.
Smith is an ASU Regents' Professor in the Department of Physics in ASU's College of Liberal Arts and Sciences.
They'll focus on deepening knowledge of the basic properties of materials used to construct lasers and infrared photodetectors. They'll study the origins of defects in the materials and explore ways to reduce them.
Understanding how defects form at the nanometer scale will enable improvements in these materials, opening the path to advances in semiconductors, infrared photodetectors and imaging systems, Johnson says.
This is the third MURI program grant awarded to ASU researchers in the past several years in semiconductor optoelectronics
