Opis

Electron Energy Loss Spectroscopy (EELS) is a high resolution technique used for the analysis of thin samples of material. The technique is used in many modern transmission electron microscopes to characterise materials. This book provides an up-to-date introduction to the principles and applications of EELS. Specific topics covered include, theory of EELS, elemental quantification, EELS fine structure, EELS imaging and advanced techniques.

Recenzje

'The real strength of this book shines through on the many experimental details, where the author writes with great authority ... The wide use that I anticipate for his book will be well deserved.' - Journal of Microscopy

'As a clearly written introduction to the EELs technique, this 48th handbook is a winner.' - Bulletin of Microscopical Society of Canada and MICRON
