Scanning Probe Microscopy (SPM) is a group of methods, like Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM), that uses a probe to sense a probe-to-surface atom interaction. By two-dimensional scanning of the probe on the surface, a high resolution microscopic image is produced.

STM provides electron density maps of the frontier molecular orbitals. nc-AFM provides images of the molecular skeleton. Combining these two information is important to precise the interpretation of the STM images of molecular orbitals. Abstract.

STM is also only possible with conductive samples (which many materials are not), so high-resolution AFM allows for a new avenue of characterization for interesting semiconductor and insulator nanomaterials. Gone are the days when sub-nanometer molecular resolution was the province of only STM.

PHYSICAL REVIEW B 90, 085421 (2014) Mechanism of high-resolution STM/AFM imaging with functionalized tips Prokop Hapala* Institute of Physics, Academy of Sciences of the Czech Republic, v.v.i., Cukrovarnicka 10, 162 00 Prague, Czech Republic´ STM and AFM high resolution intramolecular imaging of a single decastarphene molecule. O. Guillermet, S. Gauthier, C. Joachim, P. de Mendoza, (1 1 1) are imaged by a combination of low temperature scanning tunneling microscopy (STM) and dynamic atomic force microscopy in the non-contact mode (nc-AFM). High resolution Atomic Force Microscopy (AFM) and Scanning Tunnelling Microscopy (STM) imaging with functionalized tips is well established, but a detailed understanding of the imaging mechanism Request PDF | STM and AFM high resolution intramolecular imaging of a single decastarphene molecule | Single decastarphene molecules, adsorbed on Cu(111) and on a bilayer of NaCl/Cu(111) are With the STM one can achieve a resolution of around 0.1 nm. This is better than the AFM, and the reason for this is the exponential dependence of the distance d in the transmission coefficient, T(e) ~ exp[—4nd], that were derived in Eq. (6.40). 2010-10-24 But, because of the exponential relation of the tunneling current and distance, STM has a better resolution than AFM. In STM image one can actually “see” an individual atom, while in AFM it’s almost impossible, and the quality of AFM image is largely depended on the shape and contact force of the tip. AFM, STM, SNOM are relatively fast imaging methods allowing sub-µ resolution, in contrast with conventional optics allowing for fast and noncontact imaging, but suffering from lack of resolution according to Rayleigh criterion.

We demonstrate that the model is able to reproduce very Gross et al. created such a sharp and well-defined tip by adsorbing a CO molecule to the metal tip, demonstrating submolecular resolution on pentacene and other molecules by AFM with a resolution that exceeds STM. The CO molecule attaches to the tip with the carbon atom, and the front atom of the tip is an oxygen atom. High resolution Atomic Force Microscopy (AFM) and Scanning Tunnelling Microscopy (STM) imaging with functionalized tips is well established, but a detailed understanding of the imaging mechanism STM gives better resolution than AFM because of the exponential dependence of the tunneling current on distance. The force-distance dependence in AFM is much more complex when characteristics such as tip shape and contact force are considered. Scanning tunneling microscopy (STM) and atomic force microscopy (AFM) methods are key tools of nanoscience. One of their most remarkable achievement is the unprecedented submolecular resolution of both atomic and electronic structures of single molecules on surfaces. First real space images of molecular orbitals were obtained with STM. Gone are the days when sub-nanometer molecular resolution was the province of only STM. It is clear that next-generation AFMs like Cypher are readily reaching into that resolution realm, revealing nanoscale features that before might not have even been observable with STM. High resolution Atomic Force Microscopy (AFM) and Scanning Tunnelling Microscopy (STM) imaging with functionalized tips is well established, but a detailed understanding of the imaging mechanism is still missing.

However, it was known that the AFM could not image individual atoms, i.e., reach true atomic resolution as the STM did. The first scanning tunneling microscope (STM) was developed in 1981 by Gerd Binnig and Heinrich Rohrer at the IBM Research Laboratory in Rüschlikon, Switzerland, for the first time making individual atoms directly visible to a small group of specialists.
