Graphite atomic spacing
WebWhat is Scanning Tunneling Microscopy (STM)? Scanning Tunneling Microscopy, or STM, is an imaging technique used to obtain ultra-high resolution images at the atomic scale, without using light or electron beams. STM was invented in 1981 by two IBM scientists named Gerd Binnig and Heinrich Rohrer. WebWith a shorter wavelength, the waves are diffracted less and so the diameters of the diffraction rings decrease. Knowing the accelerating voltage and the diameter of a diffraction ring, it would be possible to estimate the atomic spacing in the graphite. Why is the electron beam deflected by a magnetic field? This is an example of the motor effect.

WebInterplanar Spacing. The interplanar spacing dhkl between adjacent planes having Miller indices (hkl) is defined as the distance between first such plane from a parallel plane passing through the origin. ... For example, in metal films grown on amorphous substrates, low-index, high atomic density planes, e.g., (111), (110), often lie parallel ...
