  • Electron Beam-Specimen Interactions and Simulation Methods in Microscopy

Introduces electron beam scattering in the context of simulation methods, since the practicing microscopist is usually concerned with the latter. Despite the availability of user-friendly software, some understanding of the underlying physics is essential, both to ‘optimise’ the simulation and recognise its limitations and to correctly interpret and/or generalise the results. The book highlights applications with examples made possible by the significant advances in instrumentation, e.g. aberration correction and monochromation, though these are limited to those of general interest, i.e. mainly imaging and spectroscopy. The text is intended to be self-contained, with derivations provided for the main results. The level of mathematics and physics assumed is largely limited to graduate level calculus and quantum mechanics. It is also assumed that the reader has some familiarity with electron microscopes and basic techniques, such as HREM, HAADF imaging and EDX, EELS spectroscopy.

Interview with Dr. Budhika Mendis

I&M: What is your main focus in research, what is your main scientific interest?

Mendis: Electron microscopy theory and its applications in photovoltaic materials

I&M: What was the reason to write the book?

Mendis: There are many electron beam simulation methods, each with its own strengths and weaknesses.

I wanted to write a book that covers all of the more widely used simulation techniques. This provides a more holistic view of electron beam scattering theory.

I&M: What is the target audience for the book?

Mendis: Graduate students working on electron microscopy.

I&M: What knowledge is prerequisite for the book?

Mendis: Some basic quantum mechanics and calculus which are covered in most physical science undergraduate degrees.

I&M: What is the structure of the book?

Mendis: Individual chapters cover Monte Carlo, Multislice, Bloch wave and Electrodynamic simulation methods. There is also a chapter on how to simulate core loss ionization scattering.

I&M: When will Electron Beam-Specimen interaction will be a standard method?

Mendis: With increased computing power electron beam-specimen interaction simulations are now arguably routine. Hence the need for a book covering the major simulation techniques.

I&M: Which field will benefit most from the new methods available?

Mendis: Materials Science, Physics and Chemistry
