Quantum Science and Technology: Applications for Daily Life

When you look closely, Nature is nanotechnology and quantum sensing 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 quantum-structures that exist to perform a specific function.
This same beauty can be mirrored when we interact with the tiny physical world which is the realm of quantum mechanics. Electrons, photons, and even thermal properties can all be engineered at this level. Using Nature as a template, researchers have already applied nanotechnology to improve traditional sensors (e.g. artificial eyes, ears, and noses). However, beyond this is the more general “quantum sensing” area, which allows us to think creatively about interacting with and exploring physical processes on a truly fundamental level.
Possibly the simplest aspect of quantum science and nanotechnology, the 2-D quantum well has dramatically enhanced the efficiency and versatility of electronic and optoelectronic devices. While this area alone is fascinating, nanotechnology has now progressed to 1-D (quantum wire) and 0-D (quantum dot) systems which exhibit remarkable and sometime 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. There is still so much to learn and to be curious about.
In this talk, Razeghi will present the latest quantum devices based on atomic and gap engineering of III-V semiconductor from deep UV(200 nm) up to THZ (300 microns).
About the Speaker
Manijeh Razeghi joined Northwestern University, Evanston, IL, as a Walter P. Murphy Professor and Director of the Center for Quantum Devices in 1991, where she created the undergraduate and graduate program in solid-state engineering. She is one of the leading scientists in the field of semiconductor science and technology, pioneering in the development and implementation of major modern epitaxial techniques. Her current research interest is in nanoscale optoelectronic quantum devices. She has authored or coauthored more than 1000 papers, more than 31 book chapters, and 18 books. She holds 55 U.S. patents and has given more than 1000 invited and plenary talks. She received the IBM Europe Science and Technology Prize in 1987, the Achievement Award from the SWE in 1995, the R.F. Bunshah Award in 2004, the IBM Faculty Award in 2013, and many best paper awards. Dr. Razeghi is an elected Fellow of SWE (1995), SPIE (2000), IEC (2003), OSA (2004), APS (2004) IOP (2005), IEEE (2005) and MRS (2008). She is editor, associate, and board member of many journals, including Nanoscience and Nanotechnology.
