  • ADSORBATE ANALYSIS USING OPTICALLY STIMULATED ELECTRON EMISSION
    Publication number: 20190339216
    Abstract: A probe for collecting optically stimulated electron emission to inspect chemical reactions of a surface includes a light source to emit light on the surface, a collector, and a controller. The light source emits light on the surface. The collector is configured to detect photoelectrons emitted from the surface in response to the light from the light source impinging on the surface. The collector is further configured to provide a photocurrent based on the detected photoelectrons. The controller includes at least one processor and is operably coupled to the light source and the collector. The controller is configured to cause the light source to emit light on the surface, receive the photocurrent from the collector, and determine at least one chemical reaction of the surface based on the received photocurrent.
