Auger electrons vs XPS spectra

Microscopic Characterization
Category General
Difficulty Level Normal
Audience Level General
Description Microscopic characterization methods refer to scientific techniques Which allow determination of both composition and structure of a material. Optical microscopy, scanning probe microscopy and electron microscopy are known as microscopic techniques. This course illustrates how microscopic characterization techniques are used.
Overview
Microscopic methods play an essential role in nanomaterials characterization. Microscopic and X-ray based characterization of nanomaterials techniques are used for the determination of surface morphology and dispersion characteristics of nanomaterials. This course deals with details of these aspects, and will provide a fundamental understanding of morphological tools, such as instrumentation, sample preparation and different kinds of analyses, etc.


Booklet
Description
 The photoelectrons are more intense, while, the auger electrons are produced in heavier elements with less efficiency. By changing the energy of the photons the Auger electrons and the x-ray photons can be separated and distinguished from each other.
Mental Challenge
 How is possible to distinguish photoelectrons from Auger electrons?
Quizzes and Activities
 Activity: Compare the difference between XPS and AES, list the differences in a table.
