An introductory level guide to electron diffraction in the TEM Gives useful case studies and examples to guide the new user User-friendly approach with simple explanations and informative illustrations Explains the basic methods of how to obtain images and patterns with the TEM, and how to interpret them. TAMs are used in many labs, and allow users to explore the structure of a specimen of interest (e.g. a section through a particular material, crystal or tissue). The TEM is used to pass electrons through a sample, and the electrons are scattered or diffracted in order to produce an image. This book looks at the patterns produced by diffracted electrons to study the appearance, orientation and structure of the sample.

'Dr Champness has mangaged to include a host of excellent features not readily found in other texts ... Perhaps the strongest feature of the book is that the plentiful examples are taken from materials with a wide range of crystal structures. Make sure it is available in your EM laboratory.' - Journal of Microscopy

'This book contains rich application examples from a specialist and should be a very useful introductory text to graduate students as well as a handy reference book for research specialists.' - Microscopy and Analysis
