Current Research:

Professor Jory Yarmoff investigates the physical and chemical properties of solid surfaces. Experimental Surface Science studies in ultra-high vacuum provide an atomic-scale picture of surface geometric, electronic and chemical structures, chemical reactions that occur at surfaces, and the interaction of radiation with surfaces. This work is part of the growing field of nanoscience, and has applications in diverse technological fields including nanoscale devices, microelectronics, catalytic chemistry, and environmental remediation.

 Prof. Yarmoff's research program involves both the application of existing Surface Science techniques to important physical, chemical, technological and environmental problems, as well as the development of new techniques. Current efforts include (1) the use of neutralization during ion scattering as a measure of the electronic structure of adatoms, molecules and nanomaterials, (2) the investigation of the composition, surface structure and chemical adsorption of novel two-dimensional materials, such as graphene and topological insulators, and (3) the development of innovative schemes for the fabrication of nanomaterials.
