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 twodimensional 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 16 books and the author of 27 book chapters. She is the author or co-author of more than 1000 papers and gave more than 500 invited and plenary talks. She holds 55 patents.

The Wonder of Nanotechnology: Quantum Optoelectronic Devices and Applications Manijeh Razeghi, Leo Esaki, Klaus von Klitzing SPIE, published 2013 When you look closely, Nature is nanotechnology at its finest. From a single cell, a factory all by itself, to complex systems, such as the nervous system or the human eye, each is composed of specialized nanostructures that exist to perform a specific function. This same beauty can be mirrored when we interact with the tiny physical world that is the realm of quantum mechanics. The Wonder of Nanotechnology: Quantum Optoelectronic Devices and Applications, edited by Manijeh Razeghi, Leo Esaki, and Klaus von Klitzing focuses on the application of nanotechnology to modern semiconductor optoelectronic devices. Electrons, photons, and even thermal properties can all be engineered at the nanolevel. The 2D quantum well, possibly the simplest aspect of nanotechnology, has dramatically enhanced the efficiency and versatility of electronic and optoelectronic devices. While this area alone is fascinating, nanotechnology has now progressed to 1D (quantum wire) and 0D (quantum dot) systems that exhibit remarkable and sometimes unexpected behaviors. With these components serving as the modern engineer's building blocks, it is a brave new world we live in, with endless possibilities for new technology and scientific discovery.

Antimony: Characteristics, Compounds and Applications Manijeh Razeghi Nove: Material Science and Technology, published 2012 his book is a collection of diverse research activities on antimony where 12 groups of prominent authors from different part of the worlds presented their latest achievement on antimony-related materials. In the past, despite being widely known and utilized by many countries and cultures, antimony's status as an alchemical substance and its high toxicity have obscured understanding of the material, resulting in controversial usage of antimony, especially in medicine. Today, knowledge about antimony compounds has tremendously increased, and the application range of antimony has become much wider. Due to the diversity of the applications of antimony, researchers may stay focused on their own field while lacking familiarity with antimony-related activities in other fields.
