Research Abstract

An absolute work function microscope, which can measure the absolute work function and can image the spatial distribution of the work function on the specimen surface, has been developed in the present study. A spherical and chromatic aberration corrected optical lens system and a high-brightness monochrometer were developed as the photon source, and the work function mapping was carried out using a photo emission electron microscope.
