Outline the process by which you could determine the crystal structure of a material using data from a TEM, stating key formulas and using drawings to help explain those formulas. Assume that you have been given a black and white, diffraction-mode image, such as shown in class. Begin your outline with how you would determine if the image represented an amorphous vs. single crystalline vs. polycrystalline material. Then, walk through the analysis you would do to that data to obtain a crystal structure and unit cell parameters. (All information needed is given in the question)
