Scanning tunneling microscopy (STM) is different to AFM, in that it uses tunneling electrons and the piezoelectric effect to generate an image of a surface. STM uses a conducting (quartz) tip to

The major difference between atomic force microscopy and competing technologies such as optical microscopy and electron microscopy is that AFM does not use lenses or beam irradiation. Therefore, it does not suffer from a limitation in spatial resolution due to diffraction and aberration, and preparing a space for guiding the beam (by creating a vacuum) and staining the sample are not necessary.

29 May 2015 asymmetry on NC-AFM and STM imaging involves the comparison of constant height images of interaction force and charge density calculated

With electron diffraction capability and EDX (energy dispersive X-ray spectroscopy), structure and elemental composition data can also be acquired. Keynote Papers Industrial Uses of STM and AFM* T.V. Vorburger', J. A. Dagata', G.Wilkening*, and K. lizuka3 Submitted by E.G.Thwaite (1) and P. Lonardo (1) National Institute of Standards and Technology, Gaithersburg, MD, USA 'Physikalisch-Technische Bundesanstalt, Bundesallee 100, Postfach 3345, Braunschweig, Germany 3Nikon Corporation, Tsukuba Research Laboratory, 5-9-1 Tohkohdai, Tsukuba We perform simultaneous atomic force microscopy (AFM) and scanning tunneling microscopy (STM) measurements on the Si(111)-(7×7) surface. 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 Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen.

En annan skillnad som kan ses är att spetsen i AFM berör ytan försiktigt vid ytan, medan i STM hålls spetsen på kort avstånd från ytan. Till skillnad från STM, mäter AFM inte tunnelströmmen utan mäter endast den lilla kraften mellan ytan och spetsen. The scanning tunneling microscope (STM) and atomic force microscope (AFM) provide, not only ‘eyes’ but also ‘hands’ to investigate and modify nano-objects. Therefore, not only are high resolution images available to us, but they offer a means to construct objects in the microscopic world. A detailed description on the Scanning probe microscope.

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).

SNI påverkar rumsligt arbetsminne och korttidsminnet (STM), men inte (b–d) There was no difference in frequency facilitation produced by 2, 4, and 8 Hz

The AFM captures images precisely by moving a manometer tip across the image surface. The STM, in contrast, captures images by making use of quantum tunneling. 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.
