The pyramidal silicon etched probes with an overall conductive platinum coating are suitable for a wide range of electrical AFM applications. The platinum coating is a 30 nm thick film on both sides of the cantilever.

Application

AFM is capable of mapping different electric properties of materials to topography images. These data can be used for analysis of the structure and composition of heterogeneous samples as well as for quantitative characterization of individual grains or defects on surface.

Electric properties of a sample can be mapped using probes with conducting coatings, when AC or DC bias is applied between the tip and the sample. Contact mode or two-pass operation technique can be used for this purpose.
