Low Dimensional Materials: Bridging the Fundamental Principles to Practice Applications provides an overview of research on low-dimensional materials, devices, and their applications. There are seven chapters in the book, starting from the basic quantum theory in chapter one, to the control and characterization of the unique structures (chapters two and four), to the relation of the physical and chemical properties with structures (chapter five), and to the practical and promising applications in energy, information, and health (chapter six), before conclusions and future outlook in chapter seven.
