ABOUT THIS WEBINAR
Nature offers us a full assortment of atoms, but quantum engineering is required to put them together in an elegant way to realize functional structures not found in nature. A particularly rich platform for the quantum era are III-V semiconductors, which are made of atoms from columns III and V of the periodic table and constitute compounds with many useful optical and electronic properties in their own rights. Guided by highly accurate simulations of electronic structures, modern semiconductor quantum devices are literally made atom-by-atom using advanced growth technology, which combines materials in ways that give them new properties that they did not have individually. Modern mastery of atomic engineering allows for the creation of high-power and highly efficient functional devices, such as those that convert electrical energy into coherent light, or devices that detect light of any wavelength and convert it into an electrical signal.

This talk presents the future trends and latest world-class research breakthroughs that have brought semiconductor quantum engineering to an unprecedented level. These breakthroughs have enabled the creation of infrared (IR) light detectors and emitters over an extremely wide spectral range: from 0.2 to 300 microns. Such detectors and emitters can now also be integrated with silicon (Si) photonics. These advancements can provide new knowledge of the universe, improvements in human and environmental health, and strengthened national security.

About the presenter:
Manijeh RazeghiManijeh Razeghi, Ph.D., received a doctorate of physics from the University of Paris, France, in 1980. She worked afterward as head of the Exploratory Materials Laboratory at Thomson-CSF in France and joined Northwestern University as a Walter P. Murphy Professor and Director of the Center for Quantum Devices in 1991. At Northwestern, she created the undergraduate and graduate program in solid-state engineering; she also funded a center for quantum devices.

She has authored or co-authored more than 1000 papers, more than 35 book chapters, and 20 books, including the textbooks Technology of Quantum Devices (Springer Science Business Media, 2010) and Fundamentals of Solid-State Engineering, 4th Edition (Springer Science Business Media, 2018). Two of her books, MOCVD Challenge Vol. 1 (IOP Publishing, 1989) and MOCVD Challenge Vol. 2 (IOP Publishing, 1995), discuss some of her pioneering work in InP-GaInAsP- and GaAs-GaInAsP-based systems. The MOCVD Challenge, 2nd Edition (Taylor & Francis/CRC Press, 2010) represents the combined updated version of Volumes 1 and 2. She holds more than 60 U.S. patents and has given more than 1000 invited and plenary talks. Her current research interest is in nanoscale optoelectronic quantum devices and systems.

Razeghi is a fellow of IOP, APS, SPIE, Optica, and the International Engineering Consortium (IEC). She is a fellow and life member of the Society of Women Engineers (SWE), IEEE, and MRS. She is also a member of Academy of Europe (AE). Razeghi's awards include the IBM Europe Science and Technology Prize (1987); the Achievement Award from the SWE (1995); the R.F. Bun shah Award (2004); the IBM Faculty Award (2013); the Jan Czochralski Gold Medal (2016); the Benjamin Franklin Medal in Electrical Engineering (2018); and many best-paper awards.
