Study of the surface chemistry of material using electron spectroscopy

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
 Electron spectroscopy is a technique for surface chemical analysis. There are two types of electron spectroscopy: Auger electron spectroscopy (AES) and X‐ray photoelectron spectroscopy (XPS). Photoelectron (PE) spectroscopy measures the binding energies of electrons in molecules. Photo-ionization is the process in which molecule (M) is ionized by a beam of photons, in which the molecule will lose an electron.
Mental Challenge
