Technical Expertise, Areas of Interest and Accomplishments:
- Dr. Razeghi is a pioneer in the area of III-V compound semiconductors and optoelectronic devices from the deep ultraviolet to the far infrared spectral bands, including in particular InP and GaAs based semiconductors and devices, which were at the heart of the optical fiber telecommunication revolution of the late 20th Century and the rise of the information age.
- From 1981 to 1991, while a Senior Research Scientist at first and then Head of the Exploratory Materials Laboratory at Thomson-CSF (Orsay, France), Dr. Razeghi developed and implemented most major modern epitaxial growth techniques such as low pressure metalorganic chemical vapor deposition (MOCVD), vapor phase epitaxy (VPE), molecular beam epitaxy (MBE), GasMBE, and MOMBE for entire compositional ranges of III-V compound semiconductors and heterostructures. Developing these tools was fundamental in enabling her to achieve high purity semiconductor crystals with a consistency and reliability that was often unmatched, thereby leading to new physics phenomena in InP and GaAs based semiconductors and quantum structures.
- Her pioneering work on InP based compound semiconductors and devices is best illustrated in her book "The MOCVD Challenge Volume 1: A Survey of GaInAsP-InP for Photonic and Electronic Applications" (Adam Hilger Press, 1989), which details the realization of some of the first high quality InP, GaInAs/InP and GaInAsP/InP materials, heterostructures and superlattices, on a variety of substrates, with the first demonstration of two-dimensional electron gas and observation of quantum Hall effect, the first two-dimensional hole gas, and the first observation of room temperature excitons in GaInAs/InP superlattices. From a more device-oriented viewpoint, as impressive is the realization of 1.3 and 1.55 μm laser diodes for optical fiber telecommunication laser sources, optical waveguides, the first InP based Gunn diode which revolutionized radar systems, as well as then futuristic monolithic integration.
- Equally comprehensive is her pioneering work on GaAs based semiconductors and devices which is described in her second book "The MOCVD Challenge Volume 2: A Survey of GaInAsP-GaAs for Photonic and Electronic Device Applications" (Institute of Physics Publishing, 1995). Some of her impressive contributions include: the first high quality GaInP/GaAs and GaInAsP/GaAs interfaces, heterostructures and superlattices, the first two-dimensional electron gas in this system, which led to the first heterojunction field effect transistor or HFET, modulation-doped FET or MODFET, two-dimensional electron gas FET or TEGFET in this system.
- In 1991, even though many institutions had repeatedly tried to bring Dr. Razeghi to the United States to join them, Northwestern University (NU) finally succeeded in convincing her to do so and qualified this as one of the most important hires at NU of the past 20 years. There, she founded the Center for Quantum Devices and concentrated her research activities on Quantum Mechanics and a wide range of Quantum Devices, including lasers, photodetectors and focal plane arrays covering a very wide spectral band from the deep ultraviolet (down to a wavelength of ~0.2 μm) to the very long wavelength infrared (~32 μm).
- She has first successfully pioneered in the area of high power aluminum free diode lasers emitting at a wavelength near 1 μm based on GaInAsP, which revolutionized the high power diode laser industry and their applications in the early 1990's, including diode pumped solid-state lasers and erbium doped optical fiber amplifiers for telecommunications. She is also the current world leader on Quantum Cascade Lasers (QCLs) based on InP. Thanks to this work, such lasers are starting to supplant several other semiconductor, solid state and gas laser technologies operating in the same waveband, thereby reshaping a portion of the infrared laser industry with expected use for high accuracy chemical and biological agent sensing, free space optical communications and pollution monitoring. Her other significant contributions in the field of semiconductor diode lasers include her research work on InAsSb based multi quantum well and strained layer superlattice interband lasers with very low threshold operating in the midwave infrared spectral band.
- Dr. Razeghi's expertise extends to photodetectors and focal plane arrays operating in the mid, long and very long wavelength infrared spectral bands (3~32 μm). In particular, she has pioneered and is a world leader in the area of InAs/GaSb type II quantum heterostructures, photodetectors and focal plane arrays. Thanks to her work on this topic, this technology is beginning to reshape the infrared sensing industry and possibly leading to a technological revolution, with a direct impact on applications such as medical and manufacturing thermal imaging, firefighting, pollution monitoring, surveillance, law enforcement and many others. She also realized some of the first and only Quantum Dot Infrared Photodetectors (QDIPs) and focal plane arrays on GaAs and InP. In parallel, she has pioneered in the research on a wide range of Quantum Well Infrared Photodetectors (QWIPs) on InP for mid, long and very long wavelength spectral bands (4-19 μm) and demonstrated the first multi spectral QWIP on InP.
- Her research has also led to the successful realization of infrared detectors using very exploratory thallium and bismuth based semiconductor compounds such as InTlSb, InSbBi and InTlAsSb, that of uncooled InAsSb photon detectors, and of InSb focal plane arrays.
- Finally, Dr. Razeghi is also an expert in quantum devices operating in the deep ultraviolet spectral band, with the demonstration of novel light-emitting diodes, photodetectors and focal plane arrays with world record characteristics. Such devices are expected to be at the heart of next generation fast and reliable chemical and biological agent sensors, portable water purification systems, flame sensors, furnace monitoring, ozone pollution monitors, space UV astronomy, and many other applications.
- Based on her scientific research work, Dr. Razeghi is the author of 18 books and the author of 31 book chapters. She is the author or co-author of more than 1000 papers and has given more than 500 invited and plenary talks. She holds 55 patents.
- Created the Graduate and Undergraduate Programs in Solid State Engineering (SSE) in the ECE Department at Northwestern University, a 12 course curriculum.
- Supervised 50 PhD dissertations, 19 MS theses while at Northwestern.
- Currently supervises approximately 20 PhD students, Post-Docs, Visiting Researchers, and Faculty.
