### Electron Energy-Loss Spectrometers and Filters - ppt download

Electron Energy-Loss Spectrometers and Filters XEDS can identify and quantify the presence of all elements above Li in the periodic table with a spatial resolution approaching a few atoms. EELS does even more than XEDS in that it can detect and quantify all the elements in the periodic table and is especially good for analyzing the light elements. EELS can be a challenging experimental technique; it requires very thin specimens to get the best information and understanding and processing…

### Introduction to Electron Energy Loss Spectroscopy - ppt video online download

Electron Energy Loss Spectroscopy Inelastic scattering is a fundamental scattering process in which the kinetic energy of an incident particle is not conserved (in contrast to elastic scattering). Inelastic scattering events might lead to well-defined energy losses, covering a wide energy range from 104 to 10-3 eV: Core level excitation: 100 ~ 104 eV (CLEELS) Plasmon and interband excitation: 1 ~ 100 eV (EELS) Phonon and adsorbate vibration excitation: 10-3 ~ 1 eV (HREELS)
