This is an author correction notice. The original article, "Electrostatic potentials of atomic nanostructures at metal surfaces quantified by scanning quantum dot microscopy", published in Nature Physics, contained errors in Figure 3 and its associated text. These errors have been identified and corrected to ensure the accuracy of the presented data.

The correction specifically addresses Figure 3 of the article, which displayed data related to the electrostatic potentials of atomic nanostructures on metal surfaces. Textual descriptions and analyses referring to this figure have also been modified to align with the corrected data. The authors have carefully reviewed the material and provided the necessary amendments to maintain the scientific integrity of the publication.

It is important to note that, despite these corrections, the main conclusions of the original study remain unaffected. The fundamental findings regarding the quantification of electrostatic potentials using scanning quantum dot microscopy are still valid. The correction solely aims to refine the presentation of certain data and their interpretation, without altering the central scientific message of the work.
