SEMs use a specific set of coils to scan the beam in a raster-like pattern and collect the scattered electrons. The transmission electron microscopy (TEM) principle, as the name suggests, is to use the transmitted electrons, the electrons that are passing through the sample before they...

the main phase action is scattering. Where the mass thickness of the sample is larger than the scattering Angle of the electron, the electron is less and the brightness is darker. The early transmission electron microscope was based on this principle TEM transmission electron microscope It is. Af...
