Description

The book covers all major aspects of Solid State Physics (Crystal Physics). The approach of the book is unique because it offers thought-provoking ideas about the Physics of Solids, rather than being merely a compilation of research data and statistical figures. The learning design is such that the subject of Crystal Physics is explored in terms of its applicability and not as an abstract collection of concepts. The understanding of the basics is supplemented and supported by a strong mathematical basis and reasoning.

The book is an ideal choice for Ist and IInd year engineering students across India and undergraduate as well as postgraduate students of Physics. Spread over 17 chapters, all important topics have been introduced at an elementary level, which will enable even new students of the subject to gain an insight into the fascinating world of crystals and crystallography. Besides students pursuing M.Phil and Ph.D in crystallography, professionals such as mineralogists, material scientists and solid state chemists will also find the book to be of great practical use.
