CQD Director Proff. Razeghi

Since its founding in 1991, the Center for Quantum Devices at Northwestern University has evolved from only a mere vision into a concrete world-class research laboratory, with the mission to pursue academic excellence and high-level research in compound semiconductor science and nanotechnology.

The Center for Quantum Devices has put together a comprehensive facility for solid state research. This Includes semiconductor thin film epitaxial growth, material characterization, material processing and device fabrication, thin film deposition, and device packaging and measurement. The facility occupies a total of 8,000 square feet of laboratory and office space. 3,000 square feet of this total are clean room space in Cook Hall, specifically designed by Professor Razeghi.

The Center for Quantum Devices has established a proven research track record covering areas such as: high-power quantum cascade lasers, type-II superlattice infrared photodetectors, quantum dot photodetectors, UV and visible lasers, LEDs, photodetectors, and avalanche diodes, quantum well infrared photodetectors, uncooled InAsSb photodetectors, InTlAsBiSb detector technology, aluminum-free high power lasers, and antimony based 3 to 5 μm lasers.

For a comprehensive overview of the Center for Quantum Devices and the work currently being conducted here please see this 60 minute video presentation. Additional video related to Professor Manijeh Razeghi, the Center for Quantum Devices, and our research can be found on the CQD's YouTube Channel.
