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
 In this section the possibility of using other wave with the wavelength in the range of few angstrom or less for the diffraction has been described. If electrons behave as a wave, however, a diffraction pattern will emerge. We can make an analogy with the diffraction of x-rays by a crystal.
Mental Challenge
 What is the difference between electron and X-ray diffraction?
Quizzes and Activities
 Activity: Explain the relation between the electron diffraction and Bragg’s law.
