Reports of China’s Basic Researchewe in the late sixties, and his group built a scanning transmission electron microscope (STEM), which attained atomic scale resolution . This was achieved by using a cold field-emitter based on an etched single crystal tungsten wire that produced electrons emerging from a 100 Å spot. A single le
