We further introduce Electrostatics-compensated s-SNOM in order to compensate undesirable electrostatic interaction, enabling in-situ probing of local electric potentials along with the pristine optical responses and topography of the sample surface. Validity of this method of artefact suppression was demonstrated on metals, dielectrics and ferroelectrics.
*We would like to thank group of Prof. S. Kehr for motivating neaspec team in development of this technique and express special gratitude for allowing us to share the results of her group's research.This work was funded by the BMBF (Grant Nos. 05K10ODB, 05K19ODB, 05K16ODC, and 05K16ODA), the Deutsche Forschungs gemeinschaft through the cluster of excellence ct.qmat (EXC 2147, project-id 390858490) as well as by the Graduate Academy of the Technische Universit¨at Dresden.
