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.

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. 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.

4. AFM resolution is better than the STM. 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.

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.

2011-07-02 · Although first microscope is an optical solution where lenses were used to magnify the images, current high resolution microscopes follow different approaches. Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM) are based on two of such different approaches. Atomic Force Microscope (AFM)

As a surface imaging technique it is traditionally used in materials research. Here, it is With a resolution of 5-10nm laterally and sub-nanometer vertically, AFM is a powerful measurement instrument for quantitative measurements of a surface. This powerful quantitative measurement is coupled with flexibility in sample surface: there are no requirements on a sample to be able to be measured by AFM except that it fits into the instrument. 2014-04-06 STM image (30 x30 nm2, VS=2.7 V, It=0.015 nA) of C60 molecules adsorbed onto nanopores of a TBB molecular network with an atomic resolution of the SiB(111) substrate and submolecular resolution of the organic network and C60 . The image shows the C60–TBB–SiB(111) interface for a very low C60 coverage (below 0.1 monolayer (ML)). • STM images of the Au(111) electrode surface (left: unreconstructed surface at positive charge densities) • STM images of the Au (100) electrode surface (right) • Au (100) electrode in 0.1 M H2SO4 at -0.25 V vs. SCE, where potential-induced reconstruction proceeds.

Stm vs afm resolution

STM requires an electric circuit including the tip and sample to let the tunneling current go through. Single crystals of V2O5(001) and V6O13(001) were imaged in ambient conditions by scanning tunneling microscopy (STM) and atomic force microscopy (AFM). Atomic-scale resolution images are compared 2015-03-31 STM technique to investigate the electrically non-conductive materials, like proteins.

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