This is a 2432 atom ZnO model.
Can you find the orientation in the model above that corresponds to the lattice arrangement in the image below? Hint: From it's final position on startup, try rotating horizontally (about a vertical axis) by about 30 degrees. Do the spacing ratios seen there match with the experimental values below? If so, could you determine the field width of the image below, give that we haven't yet bothered to put a scale bar on it.
