AFM/STM constant height images are obtained at various tip-surface distances. Force/current distance spectroscopy using the same tip apex allows us to estimate the relative tip-surface distance for each image as well as the short/long-range force and the tunneling current.

Some twenty years ago at IBM's Almaden Research Center in San Jose, in a small lab packed with high-tech equipment in the hills of Silicon Valley, IBM researchers achieved a landmark in mankind's ability to build small structures. Both AFM and STM are widely used in nano-science. 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. One set of experiments suitable for TEM-STM concerns an unknown STM tip as well as an interacting sample, which is a limiting factor in the interpretations of STM data. The same is true for the atomic force microscope (AFM). In the AFM the force is measured by the deflection of a cantilever that supports the tip.
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. AFM - is the van der Waals force between the tip and the surface; this may be either the short range repulsive force (in contact-mode) or the longer range attractive force (in non-contact mode). 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.
