Solid State Physics Principles and Modern Applications

This textbook had its origin in several courses taught for two decades (1965– 4
1985) at Brown University by one of the authors (JJQ). The original assigned 5
text for the first semester course was the classic “Introduction to Solid State 6
Physics” by C. Kittel. Many topics not covered in that text were included in 7
subsequent semesters because of their importance in research during the 1960s 8
and 1970s. A number of the topics covered were first introduced in a course 9
on “Many Body Theory of Metals” given by JJQ as a Visiting Lecturer at 10
the University of Pennsylvania in 1961–1962, and later included in a course at 11
Purdue University when he was a Visiting Professor (1964–1965). A sojourn 12
into academic administration in 1984 removed JJQ from teaching for 8 years. 13
On returning to a full time teaching–research professorship at the University 14
of Tennessee, he again offered a 1 year graduate course in Solid State Physics. 15
The course was structured so that the first semester (roughly the first half 16
of the text) introduced all the essential concepts for students who wanted 17
exposure to solid state physics. The first semester could cover topics from the 18
first nine chapters. The second semester covered a selection of more advanced 19
topics for students intending to do research in this field. One of the co-authors 20
(KSY) took this course in Solid State Physics as a PhD student at Brown 21
University. He added to and improved the lecture while teaching the subject 22
at Pusan National University from 1984. The text is a true collaborative effort 23
of the co-authors. 24
The advanced topics in the second semester are covered briefly, but thor- 25
oughly enough to convey the basic physics of each topic. References point the 26
students who want more detail in the right direction. An entirely different 27
set of advanced topics could have been chosen in the place of those in the 28
text. The choice was made primarily because of the research interests of the 29
authors. 30
In addition to Kittel’s classic I ntroduction to Solid State Physics, 7th 31
edn. (Wiley, New York, 1995), other books that influenced the evolution of 32
this book are: Methods of Quantum Field Theory in Statistical Physics ed. by 33
A.A. Abrikosov, L.P. Gorkov, I.E. Dzyaloshinsky (Prentice-Hall, Englewood, 34
NJ, 1963); Solid State Physics ed. by N.W. Ashcroft, N.D. Mermin 35
(Saunder’s College, New York, 1975); Introduction to Solid State Theory ed. 36
by O. Madelung (Springer, Berlin, Heidelberg, New York, 1978); and Fun- 37
damentals of Semiconductors ed. by P.Y. Yu, M. Cardona (Springer, Berlin, 38
Heidelberg, New York, 1995). 39
Many graduate students at Brown, Tennessee, and Pusan have helped to 40
improve these lecture notes by pointing out sections that were difficult to 41
understand, and by catching errors in the text. Dr. Alex Tselis presented 42
the authors with his carefully written notes of the course at Brown when 43
he changed his field of study to medical science. We are grateful to all the 44
students and colleagues who have contributed to making the lecture notes 45
better. 46
Both the co-authors want to acknowledge the encouragement and support 47
of their families. The book is dedicated to them
