MikroMasch Conductive AFM Probes are ideal for imaging of electric properties of materials in ambient conditions. Though silicon is conducting in bulk due to the presence of the dopants, the surface of the probe is always coated by a thin (1 - 2 nm) native oxide film. That is why using the conductivity of Si probes for AFM measurements is only possible in UHV conditions after the film is removed.
