What is Scanning Transmission Electron Microscopy (STEM)?
From this chapter, we start with studying scanning transmission electron microscopy (STEM) and its imaging theory. The STEM which uses a fine electron probe and a scanning system seems different from TEM explained in previous chapters. The image intensity is equivalent to that by TEM due to the reciprocal theorem in optics. The STEM is nowadays recognized as a very effective tool for structural and chemical analyses of nanomaterials.
