what is scanning tunneling electron microscope

  • Scanning electron microscope - Wikipedia

    A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.The electrons interact with atoms in the sample, producing various signals that contain information about the sample's surface topography and composition.
