Munir H Nayfeh


Professor Munir Nayfeh received his bachelor's and master's degrees from the American University of Beirut in 1968, and 1970, respectively. He earned a Ph.D. in physics from Stanford University in 1974. He served as a postdoctoral fellow and research physicist at Oak Ridge National Laboratory from 1974-1977, and as a lecturer at Yale University in 1977, before joining the physics faculty at the University of Illinois in 1978.

Following his arrival at the UIUC, Professor Nayfeh developed an active experimental program to study the multi-photon (nonlinear) dissociation of molecules as a means to enhance dissociation selectivity. He was the first to demonstrate isotope separation using this process. He was also the first physicist to examine the behavior of hydrogen molecules in intense laser fields, and his seminal work in this area initiated a whole new area of research in molecular Coulomb explosions.

In the past few years, Professor Nayfeh has pursued two separate lines of research: (1) a theoretical program focusing on the role of classical chaotic dynamics in hydrogen atoms rendered essentially one-dimensional in the presence of very strong dc electrical fields; and (2) an experimental program he has termed "writing with atoms," in which the spatial selectivity of the electric field in a scanning tunneling microscope (STM) is combined with the frequency (energy) selectivity of a laser to deposit fine patterns with nearly atomic resolution on a variety of substrates at room temperature. Dr. Nayfeh was solely responsible for the conception and development of this innovative technique.

Most recently, Professor Nayfeh has investigated the fabrication and the analysis of nanometer-scale structures by employing STM to study hysteresis effects in the formation of matter. This work provides physical insights on the fundamental nature and interactions of solids at nanometer/atomic scales, and it has significant implications for near-term technological applications in nanoelectronics and photonics .
