This statement is the basis for quantitative electron probe microanalysis. Castaing’s treatment can be represented by the following considerations. where NdE/dX is the mean energy change of an electron in traveling a distance X, N 0 is Avogadro’s number, ρ is the density of the material, A A is the atomic weight of A, C A is the concentration of element A, E c is the critical excitation energy for whatever characteristic x-ray line is of interest, and Q. is the ionization cross section, defined as the probability per unit path length of an electron of given energy causing ionization of a particular electron shell (K, L, or M) of an atom in the specimen.
X-ray microanalysis using a modern transmission or scanning transmission electron microscope (TEM/STEM) is an extremely powerful analytical tool. The ability to observe and characterize the morphology, crystallography, and elemental composition of regions of a specimen as small as 20 nm in diameter is a major breakthrough for materials science.
Each book of the series starts from first principles, assuming no specialist knowledge, and is complete in itself. The series will eventually cover the whole range of techniques for electron microscopy.

Quantitative X-ray microanalysis of thick samples is usually performed by measuring the characteristic X-ray intensities of each element in a sample and in corresponding standards. The ratio of the measured intensities from the unknown material to that from the standard is related to the concentration using the ZAF or ϕ(ρz) equations. This is not possible with cold field emission scanning electron microscopes (FE-SEMs) where beam current can fluctuate around 5% in its stable regime. Very little work has been done on variable beam current conditions (Griffin, . Scanning 13, 307-312, 1991), and none relating to cold FE-SEM applications.
Materials scientists, materials engineers and scientists in related disciplines, including chemistry and physics, will find this to be a detailed, method-orientated guide to microscopy methods of.
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, however, can routinely reach several angstroms on a modem instrument. In addition, the TEM can also provide material structural information, since the electrons penetrate through the thin specimens, and chemical compositional information due to the strong electron-specimen atom interactions.
