Illustrates the principle of transmission electron microscope?
Principle of Transmission Electron Microscope
The electron microscopes are worked onto the basis of, while a beam of electrons hit on a bulk material this can be either reflected or backscattered through the bulk material or the electrons share energy to the atomic electrons which are present in a solid and that can after that release secondary electrons. In electron microscopy the incoming electrons are focused through electric or magnetic field and pass by the solid specimen and amass the amplified scattered electrons and the secondary electrons through a sensor.
