"Core of a good materials engineer is built around a sound understanding of atomic structure of materials. Since electrons are the primary building blocks of atoms, this course/book introduces students to the idea that the collective behavior of electrons in a crystal affect the physical properties of that material. Given the limited background of undergraduate students in quantum physics, Prof. Haridoss designed the course to first familiarize us with basic laws of quantum mechanics and used those to explain band diagrams. As an undergraduate student I found most of my classes boring, but Prof. Haridoss' course was like a story that made me ask questions which were answered as the course progressed."
Prashant Kumar, PhD Candidate - Mkhoyan & Tsapatsis lab, Department of Chemical Engineering and Materials Science, University of Minnesota, Twin Cities.
"Being an undergraduate student of Metallurgy and Materials Science, it is of paramount importance for one to understand the influence and impact of electronic structure on properties that we observe in real day-to-day materials. For example, small changes in the band gap of a material can alter the electronic conductivity by several orders of magnitude, which is crucial in designing our semi-conducting computing circuits! Scientists in the past have come up with models (that are still being perfected as you read this sentence) to understand and explain the different electronic configurations observed in solid state materials, and Prof. Prathap Haridoss' course on the "Physics of Materials" is a very good introductory course in this context, introducing the various models in a very elegant fashion with quantitative emphasis including the statistical distribution functions."
"While Prathap is a fantastic lecturer himself, explaining the difficult concepts in detail and pacing the class in a fashion that is suitable for students who have had little exposure to quantum mechanics before, his course will be greatly aided by a book that introduces the ideas in the same fashion that he does in class. Hence, I am pretty sure this book will be a great value addition for all students (and professionals) who are eager to get a primer on this subject."
Sai Gautam Gopalakrishnan , Class of 2013, Department of Metallurgical and Materials Engineering, Indian Institute of Technology, Madras.
"I had taken Prof. Prathap Haridoss' course "Physics of Materials" as a 3rd year B.Tech student at IIT Madras in Fall semester 2004. Typically, he consolidates concepts from various books/sources, and presents what would be most relevant at Bachelor's level. Prof. Haridoss always focused on extracting physical insights, even when teaching hard-core mathematical concepts like Reciprocal lattices, Drude Model, and excerpts from statistical mechanics. An organized text book like this helps develop our physical intuition about material properties to a relatively high level. It will also help link classroom lectures and the students' broad curiosity about how material properties can/cannot be understood by theories of classical and statistical physics."

"Physics of Materials’ has a stark difference to other courses. Instead of discussing the properties of a material, it discussed why a material behaves the way that it does. It covers a wide range of topics from electrical and magnetic properties to thermal and optical properties. The study material as well as the course videos facilitated easy understanding of the wide range of topics. The most interesting part of the course for me was the section on nano-scale materials as it made me get interested in this field and thereby laid the foundation of my final project."
Pranav Vrat, Sr. Associate, Risk Management, Capital One.
"The course on ‘Physics of Materials’ was very interesting since it spoke about the behavior of materials and the reasons that cause such behavior. It was something new for us and I thoroughly enjoyed it. The course was structured differently and the course videos and study material certainly aided an easy understanding of the course. The mentoring approach and clear communication from the instructor made it easy and fun to learn. "
Ashwin Kalkar, IIM, Bangalore.
"I took the Physics of Materials course during my undergraduate study. This course relates the electronic structure of materials to their macroscopic electrical, magnetic, and optical properties properties. This is a fairly advanced course requiring understanding of concepts from quantum mechanics and we find a lot of graduate-level books on this subject. Prof. Prathap Haridoss taught this course very lucidly and made it accessible to undergraduate students. I am happy to note that he has written a book to accompany this course. I am sure it will be a comprehensive resource and a much-needed undergraduate-level book on this subject."
