Web73K views 2 years ago. This video explains the construction and working of Transmission Electron Microscope (TEM). It also discusses advantages of TEM and its applications. WebThe scanning tunneling microscope (STM) works by scanning a very sharp metal wire tip over a surface. By bringing the tip very close to the surface, and by applying an electrical voltage to the tip or sample, we can image the surface at an extremely small scale – down to resolving individual atoms. The STM is based on several principles.
