Abstract
When firing a beam of electrons at a crystal lattice, those electrons will diffract. The pattern that forms as a result of that diffraction will depend on and be unique to the crystal structure of the targeted lattice. By combining de Broglie's theory with Bragg's law, a relationship can be derived between the diffraction angle of electrons and their accelerating voltage. This relationship can then be used to determine fundamental structural information about the crystal. Using this method, the inter-planar Spacing for \(d_{100}\) and \(d_{110}\) of graphite were determined to be \(1.7 \pm 0.1 \) A and \(1.4\pm 0.2 \) A, respectively.
