Most textbooks in the field are either too advanced for students or don‎'‎t adequately cover current research topics‎.‎ Bridging this gap‎,‎ Electronic Structure of Materials helps advanced undergraduate and graduate students understand electronic structure methods and enables them to use these techniques in their work‎.‎ Developed from the author‎'‎s lecture notes‎,‎ this classroom‎-tested book takes a microscopic view of materials as composed of interacting electrons and nuclei‎.‎ It explains all the properties of materials in terms of basic quantities of electrons and nuclei‎,‎ such as electronic charge‎,‎ mass‎,‎ and atomic number‎.‎ Based on quantum mechanics‎,‎ this first‎-principles approach does not have any adjustable parameters‎.‎ The first half of the text presents the fundamentals and methods of electronic structure‎.‎ Using numerous examples‎,‎ the second half illustrates applications of the methods to various materials‎,‎ including crystalline solids‎,‎ disordered substitutional alloys‎,‎ amorphous solids‎,‎ nanoclusters‎,‎ nanowires‎,‎ graphene‎,‎ topological insulators‎,‎ battery materials‎,‎ spintronic materials‎,‎ and materials under extreme conditions‎.‎ Every chapter starts at a basic level and gradually moves to more complex topics‎,‎ preparing students for more advanced work in the field‎.‎ End‎-of‎-chapter exercises also help students get a sense of numbers and visualize the physical picture associated with the problem‎.‎ Students are encouraged to practice with the electronic structure calculations via user‎-friendly software packages‎.‎
