There're several types of electron beam microscopes which include transmission electron microscope (TEM), scanning transmission electron microscope (STEM), and scanning electron microscope (SEM). Each of these microscopes operates by accelerating an electron beam toward the surface of an object to be viewed. The scanning electron microscope observes mainly a surface mode of the specimen by detecting the secondary electron or the reflection electron being generated when a narrow electron beam (electron probe) is irradiated onto the specimen as the object by each detecto, and then displaying the image on a display screen such as the cathode-ray tube, or LCD. The transmission electron microscope can observe mainly an internal structure of the substance by passing the electron beam through a thin film specimen to get the electrons being scattered or diffracted by atoms in the specimen at that time as the electron diffraction pattern or the transmission electron-microscope image. The scanning electron microscope is the instrument of choice for the investigation of irregular surfaces both in biology materials sciences and the semiconductor industry.
