What if we could know everything there was to know about the structure of a piece of material? Complete knowledge would constitute something like a list of all the 3D positions of all atoms, with the element of each atom specified, and measurement of all the electronic states at high resolution in real and momentum space. Modern electron microscopy cannot provide quite all of that information, but it can get surprisingly close. This talk will review the basics of TEM and STEM, including imaging, diffraction, and spectroscopy, then provide examples of cutting-edge applications that measure atomic structure, defects, and electronic states in a variety of materials and in various sample environments.
