A practical guide to transmission electron microscopy : fundamentals /

Transmission electron microscope (TEM) is a very powerful tool for characterizing various types of materials. Using a light microscope, the imaging resolution is at several hundred nanometers, and for a scanning electron microscope, SEM, at several nanometers. The imaging resolution of the TEM, howe...
