A scanning tunneling microscope is a type of microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer, then at IBM Zürich, the Nobel Prize in Physics in 1986. STM senses the surface by using an extremely sharp conducting tip that can distinguish features smaller than 0.1 nm with a 0.01 nm depth resolution. This means that individual atoms can routinely be imaged and manipulated. Most microscopes are Atomic force microscopy ( AFM) or scanning force microscopy ( SFM) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction-limit .

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.

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.

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. We present a numerical STM/AFM model, which takes into account the relaxation of the probe due to the tip-sample interaction. 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.

In feedback mode, output signal usually adjusts the Z position of the scanner to maintain a tunneling current setpoint. STM is the highest resolution AFM. Probes: –TT10 –PT10 –STM High-resolution AFM/STM images with functionalized tips are typically acquired at very close distances where repulsivePauliforcesdominate.Therefore,theinfluenceoftip proximity can substantially affect the tunneling barrier [31]. Nevertheless, it has been shown [12] that the tunneling barrier The STM has a better resolution than the AFM, and both scan a specimen and provide an image with the resolution, as mentioned earlier.
