Solar panels

The Laboratory for Advanced Semiconductor Epitaxy is located in the Microelectronics Research Center at the University of Texas at Austin. We are developing advanced materials and devices for electronics and optoelectronics. We are particularly interested in GaSb-based mid-infrared quantum well lasers, THz sources based on epitaxial metal/semiconductor nanocomposites, new plasmonic materials, low-noise III-V avalanche photodiodes, silicon-based electronics/optoelectronics, and sources/detectors for quantum information processing. Our secret weapon in this effort is the molecular beam epitaxy (MBE) crystal growth technique.
