摘要
Conductive scanning probe microscopy (SPM) was applied to field-emission carbon films. The microstructures, conductivity and surface potential properties of carbon films were investigated by conductive atomic force microscopy (AFM) and Kelvin probe force microscopy (KFM), as well as a combination of the two techniques. SPM was proven to be very effective for the study of materials with multiple phases and complex structures, and in clarifying the low-field-emission mechanism.
