Written by Dr. K.D. Leaver, an experienced lecturer and research in semiconductor and optical devices at Imperial College, University of London, this book is very easy to read and almost entertaining. It focuses on explaining the working principles of three main semiconductor devices (the pn-junction, BJTs and MOSFETs) without making the mathematics intimidating. In fact, Dr. Leaver has made many simple, effective and totally legitimate assumptions to make the maths 'easy-going' to all undergraduate students. If you are interested in semiconductor devices, this 'semiconductor lite' may even make for a bed-time reading. I am honored to have been one of his students and I cannot describe how much I have benefited from this book. I am now working in semiconductor related topics in the graduate level, and I would not have started without this book. I still have a copy.
