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 the...

The working principle is based on the generation of electron-hole pairs by the backscattered electrons that escape the sample and are absorbed by the detector. The amount of these pairs depends on the energy of the backscattered electrons. The p-n junction is connected to two electrodes, one ...

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...
