Description

This class discusses the origin of electrical, magnetic and optical properties of materials, with a focus on the acquisition of quantum mechanical tools. It begins with an analysis of the properties of materials, presentation of the postulates of quantum mechanics, and close examination of the hydrogen atom, simple molecules and bonds, and the behavior of electrons in solids and energy bands. Introducing the variation principle as a method for the calculation of wavefunctions, the course continues with investigation of how and why materials respond to different electrical, magnetic and electromagnetic fields and probes and study of the conductivity, dielectric function, and magnetic permeability in metals, semiconductors, and insulators. A survey of common devices such as transistors, magn This class discusses the origin of electrical, magnetic and optical properties of materials, with a focus on the acquisition of quantum mechanical tools.

Electrons and their interaction with the specimen

Description

This is a third edition of the Electron Microscopy and Analysis textbook, which was published by Taylor and Francis Books UK in 2001 (ISBN 0748409688). It deals with several sophisticated techniques for magnifying images of very small objects by large amounts - especially in a physical science context. Consisting of seven chapters, presented as separate files the resource incorporates questions and answers in each chapter for ease of learning. Equally as relevant for material scientists and bioscientists, this resource is an essential textbook and laboratory manual. The chapter explains the behaviour of electrons within a specimen and shows how they interact with the atoms of the sample.
