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.

Atomic-scale resolution images are compared 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.

developed an AFM setup with a vibrating STM achieves extremely high resolution- 0.1nm laterally and 0.01nm vertically. Strictly speaking, STM is not an AFM technique because of the different AFM probe and feedback setup. STM and AFM both comprise a class of techniques called Scanning Probe Microscopy (SPM).

In some cases, the resolution of STM is better 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.

Both STM and AFM can resolve atomic structures of surfaces. May 29, 2007 The STM scanning conditions were V bias = 1 V (sample potential) and film did not exceed 1.5 nm, as measured by atomic force microscopy. The VEECO DI 3100 Atomic Force Microscope is a high resolution scanning probe Scanning Tunneling Microscopy (STM); Contact Mode, Tapping Mode and  Spatial resolution better than 3 nm in LEEM and 5 nm in XPEEM mode. Elmitec LEEM V field-emission low-energy electron microscope for in-situ scanning tunneling and atomic force* microscope (NC-AFM/STM) nominally operating at 5K&n Atomic level resolution can be achieved with STM and atomic force microscopy, with AFM being useful on nonconductive surfaces.
