Manijeh Razeghi

Manijeh Razeghi is the Walter P. Murphy Professor of Electrical and Computer Engineering at Northwestern University’s McCormick School of Engineering. She directs the Center for Quantum Devices (CQD), a world-class research laboratory established in 1992 with a focus on compound semiconductor science and nanotechnology. The Center specializes in developing advanced quantum devices such as lasers, photodetectors, and quantum cascade lasers, emphasizing interdisciplinary collaboration between academia, industry, and national laboratories.

Her research interests span ultraviolet to terahertz photonics, including III-nitride semiconductors, antimony-based lasers, quantum dot devices, and nanotechnology. Under her leadership, the CQD has produced over 725 publications, 60 patents, and 152 awards. Key achievements include high-power quantum cascade lasers, Ga₂O₃ heterostructures, and breakthroughs in infrared photodetectors.

Razeghi’s work integrates solid-state physics, quantum mechanics, and materials science to address cutting-edge challenges. Notable projects include room-temperature terahertz lasers grown on silicon, high-efficiency quantum cascade lasers, and self-powered oxide sensors. Her contributions have been recognized through prestigious conferences and international collaborations.

The CQD also prioritizes education, training future leaders in semiconductor technology through graduate and undergraduate programs. Current research focuses on advancing Ga₂O₃ thin films, type-II superlattices, and novel materials for high-temperature detectors. The Center collaborates with industry partners to commercialize innovations in power electronics and optoelectronics.
