Epitaxial growth lies at the heart of a wide range of industrial and technological applications. Breakthroughs, experimental and theoretical, allow actual atom-by-atom manipulation and an understanding of such processes, opening up a totally new area of unprecedented nanostructuring. The contributions to this title are divided into five main sections, taking the reader from the atomistic details of surface diffusion to the macroscopic description of epitaxial systems. many of the papers contain substantial background material on theoretical and experimental methods, making the book suitable for both graduate students as a supplementary text in a course on epitaxial phenomena, and for professionals in the field.
