Thickness measurements with electron energy loss spectroscopy [PDF]
Microscopy Research and Technique, 2008 AbstractMeasurements of thickness using electron energy loss spectroscopy (EELS) are revised. Absolute thickness values can be quickly and accurately determined with the Kramers‐Kronig sum method. The EELS data analysis is even much easier with the log‐ratio method, however, absolute calibration of this method requires knowledge of the mean free path ...
