• Brief History of Valleytronics; Valley Physics in 2D Materials; Valley Addressability — Screening for Valley Contrast; Valley Controllability — The First Experiments; Material Preparation and Development for Valleytronics; Valley Current Generation and Detection; Valley Device Engineering; Valley-Polarised Single Photons; Opportunities for Applications — Are We Ready for Valleytronics?;

"This is a timely book — the field of valleytronics is emerging and I have yet to see a book on this topic; and the field of 2D materials is just publishing its first books. Valleytronics in 2D Materials introduces the brief history of valleytronics, the valley physics of 2D semiconductors, and recent attempts to engineer valley devices for practical purposes. The field is still developing, and this book will provide a useful reference for researchers in the field."; Andrew Wee, Professor of Physics, National University of Singapore; Director, Surface Science Lab, National University of Singapore; Fellow, Institute of Physics, UK; Associate Editor, ACS Nano; "The lead author, Professor Johnson Goh, is a renowned expert in the field of valleytronics, and I believe the book will be truly appreciated by the research community not just in the field of 2D materials, but also in the areas of quantum information, quantum technology, and electronics engineering, to name but a few. Valleytronics in 2D Materials is extremely timely — the field of 2D materials has advanced beyond pure research and entered the engineering and technology areas. It will serve as a practical guide for students, researchers, and entrepreneurs interested in understanding and working in this rapidly developing research field ... The book structure is well-thought and comprehensive ... I totally recommend this book!"; Artem Mishchenko; National Graphene Centre; University of Manchester, UK;
