High-resolution imaging is a primary function of Atomic Force Microscopy (AFM), and the related applications are continuously expanding with the ongoing instrumental developments. An operation at small scales (<100 nm) has a number of factors that influence the signal-to-noise ratio and spatial resolution of the images. ... Access Full Source

Pseudoatomic Resolution In AFM Imaging Of HOPG
A possible way to achieve atomic resolution in AFM imaging on open air [1, 2] is using of the stick-slip effect (see. 2.6.5 and 4.1 of SPM basics). In this mode, the probe motion is jogging with retardation in minima of the interaction potential that correspond to atoms of the atomic surface. ... Get Content Here

How AFM Works 2-1 Contact Mode - YouTube
In this method, the cantilever scans across a sample surface. Because the cantilever is in contact with the surface, strong repulsive force causes the cantilever to deflect as it passes over ... View Video

AFM Beginner's Guide
Atomic force microscopy (AFM) is a technique to obtain images and other information from a wide variety of samples, at extremely high (nanometer) resolution. AFM works by scanning a very sharp (end radius ca. 10 nm) probe along the sample surface, carefully maintaining the force between the probe and surface at a set, low level. ... Retrieve Full Source

Quantum Microscopy - Wikipedia
Quantum microscopy is a novel tool that allows microscopic properties of matter and quantum particles to be measured and directly visualized. There are various types of microscopy that use quantum principles. The first microscope to make use of quantum concepts was the scanning tunneling microscope, which paved the way for development of the photoionization microscope and the quantum ... Read Article

Fundamental Theory Of Atomic Force Microscopy
How does AFM work? AFMs operate by measuring force between a probe and the sample. Normally, the probe is a sharp tip, which is a 3-6 um tall pyramid with 15-40nm end radius (Figure 1). Though the lateral resolution of AFM is low (~30nm) due to the convolution, the vertical resolution can be up to 0.1nm. Figure 1. ... Access Full Source

Lecture 10: Basics Of Atomic Force Microscope (AFM)
Brief History of AFM Atomic force microscopy (AFM) was developed when people tried to extend STM technique to investigate the electrically non-conductive materials, like proteins. In 1986, Binnig and Quate demonstrated for the first time the ideas of AFM, which used an ultra-small probe tip at the end of a cantilever (Phys. Rev. Letters, ... Access This Document

Atomic Resolution - People.clarkson.edu
Its twin, the AFM technique, potentially is able to provide atomic resolution imaging on any surface. However, it was known that the AFM could not image individual atoms, i.e., reach true atomic resolution as the STM did. Instead of that only an “averaged” atomic picture could be obtained, which is an artifact of friction. ... View Document
