Industry
Research efforts are directed toward investigating quantum dots for infrared detectors, exploring the infrared applications of III-nitride quantum structures, designing multi-junction concentrators that contains diluted nitride heterojunctions for high efficiency and high performance photovoltaic devices, probing intersubband transitions for long wavelength infrared detectors and quantum cascade lasers, investigating impurities and dopant incorporation in nanostructures and heterojunctions, and exploring new quantum structures for novel devices
Academics
Our current research is directed toward investigating semiconductor quantum structures, including quantum wells, quantum dots, and nanorods for electronic and optoelectronic applications. While the objective and focus are changing depending on the properties of the new quantum structures, the main emphasis remains on the following:
- Growth of quantum structures using molecular beam epitaxy and chemical vapor depositions.
- Evaluation of materials properties including optical, electrical and structural characterization.
- Device processing including infrared detectors, long wavelength infrared detectors, photovotaic devices, edge-emitting laser diodes, VCSLs, and HFETs, etc.
- Device fabrication, evaluation, and testing.
- Theoretical modeling of materials and devices including band structure calculations.
