Kramers Kronig Analysis in Electron Energy Loss Spectroscopy

摘要

Kramers Kronig analysis extracts information about the dielectric function from the low loss part of the electron energy loss spectrum. Problems with poor energy resolution are encountered when performing the Kramers Kronig analysis on energy loss data acquisited in an electron microscope. The sensitivity of the analysis is demonstrated using the Lorentz Drude model. Results from Electron Energy Loss Spectroscopy (EELS) measurements on carbon nitride are given and discussed.
