研究领域

Our fundamental interest is the study, comprehension and control of surface and interfacial processes. The systems that we are currently interested in include organic self-assembled monolayers (SAMs) bound to metal surfaces (e.g., Au, Ni, Pd, Rh, Hg, Ga), organometallic film precursors (e.g., Fe(CO)5, Ni(CO)4, Al(CH3)3 ), and composite materials for selective catalysis and electrocatalysis. By exploring the molecular dynamics of these species in well-controlled environments, we hope to be able to increase the selectivity of surface reactions and enhance the mechanical properties of atomically-thin films. Please visit the Research page for project-specific information on what we have done and where we are going. Our techniques include infrared spectroscopy (IRRAS, DRIFTS), electron-emission spectroscopy (XPS, AES, UPS, 2PPE) scanning probe methods (STM, AFM, STS), low-energy electron beam irradiation and high-temperature catalytic reactions; our instrumentation is typically designed and built by us due to its specialized nature.
