Developing a Super-Resolution Method for Atomic Force Microscopy

WebSince the true resolution limit of AFM imaging is dependent on the geometry of the probe tip, logic dictates that to maintain the highest image quality for the longest amount of time consideration must be taken to preserve tips during and across multiple scans. Contact mode, the most basic AFM operation technique, requires the probe to be ... WebMar 12, 2006 · Z resolution is about 0.1nm for a well-designed AFM or STM. Optical microscopes and SPMs are the easiest to use, with little or no sample preparation and no vacuum required. Optical microscopes and SEMs can have larger fields of view, but SPMs provide the highest magnifications and resolution in 3D. 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. dr maurice wollin
