Electron Beam–Specimen Interactions and Simulation Methods in Microscopy

A detailed presentation of the physics of electron beam–specimen interactions

Electron microscopy is one of the most widely used characterisation techniques in materials science, physics, chemistry, and the life sciences. This book examines the interactions between the electron beam and the specimen, the fundamental starting point for all electron microscopy. Detailed explanations are provided to help reinforce understanding, and new topics at the forefront of current research are presented. It provides readers with a deeper knowledge of the subject, particularly if they intend to simulate electron beam–specimen interactions as part of their research projects. The book covers the vast majority of commonly used electron microscopy techniques. Some of the more advanced topics (annular bright field and dopant atom imaging, atomic resolution chemical analysis, band gap measurements) provide additional value, especially for readers who have access to advanced instrumentation, such as aberration–corrected and monochromated microscopes.

Electron Beam–Specimen Interactions and Simulation Methods in Microscopy offers enlightening coverage of: the Monte–Carlo Method; Multislice Simulations; Bloch Waves in Conventional and Analytical Transmission Electron Microscopy; Bloch Waves in Scanning Transmission Electron Microscopy; Low Energy Loss and Core Loss EELS. It also supplements each chapter with clear diagrams and provides appendices at the end of the book to assist with the pre–requisites.

A detailed presentation of the physics of electron beam–specimen interactions Each chapter first discusses the background physics before moving onto simulation methods Uses computer programs to simulate electron beam–specimen interactions (presented in the form of case studies) Includes hot topics brought to light due to advances in instrumentation (particularly aberration–corrected and monochromated microscopes)

Electron Beam–Specimen Interactions and Simulation Methods in Microscopy benefits students undertaking higher education degrees, practicing electron microscopists who wish to learn more about their subject, and researchers who wish to obtain a deeper understanding of the subject matter for their own work.

BUDHIKA G. MENDIS, PhD, is Associate Professor at the Department of Physics, Durham University, UK, where he teaches electron microscopy at both undergraduate and postgraduate levels. He has over 15 years of experience in all the major electron microscopy techniques, including aberration–correction, and has used many of the simulation methods discussed in this book as part of his own research.
