Practical Electron Microscopy and Database

The terms ‘electron spectroscopy imaging’ (ESI) [1] and ‘image spectroscopy’/‘imaging spectrum’ (IS) [2 - 4] have been commonly used for methods acquiring EFTEM series. In contrast, the term ‘spectrum-imaging’ (SI) [5 - 6] is used for acquiring similar three-dimensional data blocks by STEM.

Note that the use of a large convergence angle, as occurs in the STEM mode with a focused probe minimizes the problem of electron channeling in EELS measurements.
