👉 The term "toscanite" is a technical term used in the field of optics and crystallography. It refers to the process of using scanning tunneling microscopy (STM) to study the structure of materials at the atomic level, which involves applying a high voltage to an electron beam that passes through a thin layer of material on which it has been deposited. In STM, the electron beam is directed perpendicular to the surface of the sample. As the electron beam approaches the surface, it creates
