Hi everyone, I am currently studying solid state physics from the book by Kittel(8th ed). But in this book, the chapters are like a summary of each topic and detailed explanations do not exist. While proving a formula, several steps are omitted and just the results are given. For this reason i am looking for another book. Can you suggest me any book on solid state physics in which explanations, formula proofs etc are given in a much more detailed way?
