Abstract
In subsurface imaging applications, contrast in EFM depends on the electrostatic force between the tip and sample. In the related technique, scanning Kelvin force microscopy (SKFM) contrast arises from the force due to capacitance gradient with tip-to-sample distance (dC/dz). These measured quantities arise from variations in sample dielectric constant, any charge accumulated on subsurface structures, and subsurface variations in conductivity. Our technique allows us to independently bias the subsurface structures and thereby, separate the effect of buried charge and capacitance gradient.Proceedings Title
