It has relatively good resolution, though not as good as scanning tunnelling microscopy (STM). 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 STM, SEM and AFM Images of Carbon Based Films STM and SEM Images of Carbon Nanotubes, Amorphous Carbon and Other Field Emission Materials Grown in our Laboratory STM image of carbon nanotubes obtained in our laboratory. The nanotubes stick out of the carbon soot material in the region indicated by the arrow. Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM) or scanning force microscopy (SFM) are inventions of Scanning Probe microscopy a technique that forms images of surfaces using a physical probe that scans the specimen. 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.

AFM can provide 3-dimensional information of the surface though SEM only gives a 2-dimensional image. 3. There is no special treatments for the sample in AFM unlike in SEM where many pre-treatments to be followed due to vacuum environment and electron beam.

Scanning Probe Microscopy (SPM) is a group of methods, like Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM), that uses a probe to sense a probe-to-surface atom interaction. By two-dimensional scanning of the probe on the surface, a high resolution microscopic image is produced. 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).

The discs are supplied in PELCO ® AFM/STM Disc Carriers. They are available in 10, 12, 15 and 20mm diameter. AFM head for Si cantilever: Available. All commercial cantilevers can be used: Type of cantilever detection: Laser/Detector Alignment: Probe holders: Probe holder for air measurements. Probe holder for liquid measurements. Type of AFM head mounting: Cinematically mount. Mount accuracy 150 nm (Remove/mount accuracy) STM AFM head for wire probes Atomic force microscopy (AFM) is a 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.The information is gathered by "feeling" or "touching" the surface with a mechanical probe.

Scanning Tunneling Microscopy (STM) is one of the application modes for Park AFM. STM is the ancestor of all atomic force microscopes. It was invented in 1981 by Gerd Binnig and Heinrich Rohrer at IBM Zurich.
