Abstract

Advanced atomic force microscopy based techniques were developed to investigate local properties of individual well-separated adsorbed molecules, which can be applied to all kinds of supporting substrates independent of their conductivity. First, we find that due to the Smoluchowski effect a localized electrostatic dipole moment is present at the end of metallic tips. Since its positive pole points towards the surface, we are able to identify the chemical species in atomically resolved images on polar surfaces. We employed such tips to determine the exact adsorption geometry of single molecules on ionic bulk insulators. Moreover, we were able to detect magnitude and direction of the electrostatic dipole moment of adsorbed molecules. Secondly, if the tip is magnetic, we are even able to probe the short-range electron-mediated magnetic exchange interaction between the foremost tip apex atom and the sample atom directly below and thus established magnetic exchange force microscopy as a novel method to study magnetic sample systems with atomic resolution. By applying this new kind of magnetically sensitive force microscopy to a paramagnetic organo-metallic complex adsorbed on an antiferromagnetic bulk insulator, we find indications for a superexchange-mediated coupling between molecule and substrate.

Footnotes
1
The effective size of a tip is always related but not necessarily identical to its geometric size. For example, the lateral resolution of magnetic force microscopy (MFM) is related to the spreading of the magnetic field that emanates from the tip, which is much larger than its geometric size. However, sharp tips generally produce a more localized field.
 
2
True atomic resolution in the non-contact mode or in the weakly repulsive regime allows to detect point defects. AFM in contact mode only resolves the periodicity of a surface, because many atoms are in contact with the surface.
 
3
The repulsive regime is not accessible in a controllable manner employing constant \(\Delta f\) imaging, because the working curve of the z-feedback loop, i.e., \(\Delta f(z)\), is not monotonous, but follows the general form of a Lennard–Jones potential.
 
4
The situation can be more complex, if the tip apex atoms are not close-packed (usually a justified assumption for stable tip apices) or if more than one chemical species are present at the tip apex.
 
5
Apparently, the formation of a chemical bond disturbs the mechanism that leads to intramolecular atomic resolution, because reactive tips, e.g., pure metal tips, are seemingly unable to achieve a similar resolution. If approached too close, the strong chemical interaction probably induces tip changes or sample modifications.
