Scanning Force Microscope (SFM) or Scanning Probe Microscope (SPM), has been around for almost 15 years. The microscope was an offshoot of the Scanning Tunneling Microscope (STM) and designed to measure the topography of a nonconductive sample. The AFM has undergone several enhancements over the years, allowing it to measure the local resistivity, temperature, elasticity, tribology, as well as allowing studies beyond the limitations of conventional STM - is the tunnelling current between a metallic tip and a conducting substrate which are in very close proximity but not actually in physical contact.

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. Rev. Letters, STM AFM The size of the tip and the resolution IT: exponential dependence of distance tip-sample, closest atom of tip interacts with surface atomic resolution is achieved Several atoms of the tip interact with the sample surface, every atom of the tip „sees“ a shifted lattice with respect to the lattice seen by the neighbor atom 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.

Surface. Sample must be conductive material and must be in a vacuum. Can be used to manipulate atoms on the sample surface.

the STM tip with a standardAFM-cantileverchip,a new com-bination was demonstrated: TEM-AFM. Here the force was simply measured by direct TEM imaging of the motion of the AFM tip. Some experimental results are included to illustrate the capabilities of TEM-STM and TEM-AFM.
