Major Research Interests

An important aspect of future research is based on advancing understanding in problems related to electronically nonadiabatic energy transfer at surfaces. Electronically non-adiabatic effects refer to Born-Oppenheimer approximation (BOA) breakdown where energy can be converted back and forth between nuclear and electronic motion. While electronically nonadiabatic interactions have been observed in other physical contexts – for example gas-phase and liquid-phase energy transfer – for molecular interactions at surfaces; they appear to be of central importance. For example, observations of electron emission from low work function surfaces resulting from collisions of highly vibrationally excited molecules give direct evidence of the conversion of internal (vibrational) energy of a molecule. Such behavior is of significant interest to energy conversion research as it represents an entirely new field of inquiry into how elementary atomic scale energy conversion processes take place, where chemical and electrical energy are intrinsically interrelated. The theoretical basis for the first-principles understanding of this class of phenomenology is still in its infancy. Thus, new experiments motivate new theoretical developments and vice versa. Furthermore, as our understanding of such elementary energy conversion processes improves, we may predict behavior and attempt to exploit our new knowledge to create conditions for unexpected new kinds of energy conversion.
