Atomic force microscopy (AFM) sometimes referred to as scanning force microscopy (SFM) is a microscopy technique used to give a topographical image of a surface i.e. allows the analysis of the shape and features of the surface. It has relatively good resolution, though not as good as scanning tunnelling microscopy (STM).

Islands having a 3x1 reconstruction are observed. 2005-04-28 Further, the ultimate energy resolution for spectroscopy has been improved to < 1 meV, ideal for work with superconducting materials. When combined with the MATRIX 4 controller and its new, high performance PLL, performing QPlus® AFM experiments in the LT STM will be easier and more powerful than any other QPlus® AFM platform. 2005-05-01 Atom corrals presented by Don Eigler and coworkers, IBM Almaden Research Center.

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. The STM was the first instrument to generate real-space images of surfaces with so-called "atomic resolution." This would later be known as atomic lattice resolution. The operation of STM and Conductive AFM is identical except that one uses a sharpened and conducting wire/tip in STM instead of a conductive AFM cantilever. In principle, AFM can provide higher resolution than SEM. It has been shown to give true atomic resolution in ultra-high vacuum (UHV) and, more recently, in liquid environments. High resolution AFM is comparable in resolution to scanning tunneling microscopy and transmission electron microscopy. Brief History of AFM Atomic force microscopy (AFM) was developed when people tried to extend STM technique to investigate the electrically non-conductive materials, like proteins. In 1986, Binnig and Quate demonstrated for the first time the ideas of AFM, which used an ultra-small probe tip at the end of a cantilever (Phys.

The STL technique combines scanning tunneling microscopy (STM) with detection of photons, induced by the tunneling electrons. The high spatial resolution in

STM, which uses a metal needle as the afm tip, is one of the highest resolution AFM techniques.

According to the different working principles though, they have their own advantages and disadvantages when measuring specific properties of sample (Table \(\PageIndex{1}\)). STM requires an electric circuit including the tip and sample to let the tunneling current go through. Two of the most common are Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM).
