      abstract     = {We present a multi-tip scanning tunneling potentiometry
                      technique that can be implemented into existing multi-tip
                      scanning tunneling microscopes without installation of
                      additional hardware. The resulting setup allows flexible in
                      situ contacting of samples under UHV conditions and
                      subsequent measurement of the sample topography and local
                      electric potential with resolution down to Å and μV,
                      respectively. The performance of the potentiometry feedback
                      is demonstrated by thermovoltage measurements on the
                      Ag/Si(111)−(3√×3√)R30∘Ag/Si(111)−(3×3)R30∘surface
                      by resolving a standing wave pattern. Subsequently, the
                      ability to map the local transport field as a result of a
                      lateral current through the sample surface is shown on
                      Ag/Si(111)−(3√×3√)R30∘Ag/Si(111)−(3×3)R30∘ and
                      Si(111) − (7 × 7) surfaces.},
