SURFACE POTENTIAL MICROSCOPY (SPOM)

Surface potential microscope (SPoM) has the function of simultaneously measuring surface topography and surface potential (VDC) information. Based on the macro-Kelvin method, the Tapping Mode is used to acquire the terrain through the conductive afm tip, and the potential information is extracted by applying AC and DC voltage to the afm tip. Among them, the total voltage acting on the tip is: V = VDC + VAC sin (Ωt). The DC voltage of each tip is adjusted to zero through a dedicated feedback loop, so that the contact potential difference between the tip and the surface of each pixel is zero, so that DC becomes a measure of the surface potential.
