Abstract:

To purchase the equipment to augment and enhance research capabilities to measure the near-field optical and photoelectrical responses of electrocatalyst model systems. Through a combination of IR near-field scanning optical microscopy NSOM and illuminated kelvin-probe force microscopy KPFM the PI will map the optoelectronic response of electrocatalysts with unprecedented spatial resolution, less than 100 nm. Through IR NSOM the PIs group will elucidate the field enhancements dependence on different nanostructures shapes by locally mapping transmissionreflection. Using a novel method recently developed by Leites group, illuminated-KPFM, they will spatially resolve the chemical potential of the electrocatalytic reactions.
