Because of the digital character of AFM data, linescans can be generated from any part of the image, and it is also possible to measure … WebJan 19, 2024 · As a scanning probe technique, one can imagine an AFM working like a record player. Where a record player has a sharp needle that is deflected to produce sound, an AFM has a sharp needle whose deflection is observed to record a topography. By raster scanning the AFM tip over a sample surface, the topographical image is easily recorded.

WebAtomic-force microscopy (AFM) is a surface scanning technique that has sub-nanometer scale resolution. AFM describes a group of techniques used for non-destructive surface studies at the nanoscale. They have a resolution on the order of 103 times better than optical microscopy’s resolution limit. WebAtomic Force Microscopy (AFM) measures surface topography of materials with sub-nm vertical resolution. The technique delivers fast data, with simple scans requiring only a few minutes to complete. Strengths Best height resolution among surface topography techniques High lateral resolution with specialized cantilever tips
