This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.


Electron energy loss spectroscopy (EELS) is related to electronic, optical and mechanical properties of the observed materials. Actually, the EELS in the low-energy loss region less than 50 eV is particularly called valence electron energy loss spectroscopy (VEELS). This low loss region mainly reflects:
        i) Excitation of valence band electrons (outer shell electrons), such as interband transition (single excitation) and plasmon excitation (collective excitation).
        ii) Electronic structure.

Both i and ii) above determine the optical properties of materials.
