Angels on the head of a pin? It almost seems so as we learn to build devices so small that billions of them fit in an area smaller than a postage stamp. Nasser Peyghambarian, professor of Optical Sciences and chair of Photonics and Lasers at UA, describes the world of the very small, together with current and future applications, and the “Frontiers of Nanotechnology” at the Arizona Senior Academy on Wednesday (Dec. 4) at 2:30 p.m.

The current definition of nanotechnology includes anything with feature sizes of less than 100 nanometers, which is 100 billionths of a meter, or about four millionths of an inch; so small that only very sophisticated laboratory microscopes can even see these devices.

The ability to build such tiny devices allows, for example, semiconductor companies to build chips with billions of transistors on a single small slice of silicon. This then engenders the development and production of many of the devices that we now almost take for granted, such as cell phones. As the ability to build ever-smaller nanotechnology continues, so does the ability to create smarter and smaller technology.

Peyghambarian received a B.S. degree in 1976 from Pahlavi University (Iran) and completed his studies at Indiana University, where he earned a M.S. degree in 1979 and a Ph.D. in 1982. In addition to his UA teaching duties, he is director of the National Science Foundation Engineering Research Center for Integrated Access Networks.

His ASA talk will discuss the current state of nanotechnology, where it is headed in the future and the implications for electronics, optics, communication, medicine – and much more.
