In this post we will see *Introduction to Semiconductor Theory* by *A. Anselm*.

## About the book

This book has been written mainly for the benefit of people engaged in experimental work in the field of semiconductor physics. It will probably prove useful to students specializing in physics. Among the principal subjects treated in this book are crystal lattice vibrations, the laws of electron motion in an ideal and a perturbed periodic fields, the kinetic equation and transport phenomena (electric current).

The reader must be familiar with mathematics, quantum mechanics and physical statistics within the limits specified in the curricula of physical faculties of universities or physical and mathematical faculties of polytechnical colleges. He or she need not have a detailed knowledge of those courses but is expected to be able to find a way through the appropriate sections of textbooks referred to.

The special feature of the book is that those elementary facts are used to derive all the formulae. This, I hope, is done meticulously enough to make the book comprehensible for the above mentioned category of readers.

Some mathematical derivations of a more complex nature and less connected with the main text are presented in the end of the book in Appendices.

The book was translated from the Russian by M. M. Samokhvalov and was first published by Mir Publishers in 1981.

thank you so much for the work you are doing! š

it cannot be measured how precious your work is for all of us!

keep rocking!

hug

giulio

great work, but some letters, words on the left side of the page are quite faint !

Any way we have to manage !

You are correct. The spine of the the book was tight, so to press it harder would have damaged the book. This problem is only in the beginning, later the print is clear.
