Nearly 80% of all chemical reactions in nature and in human technology take place at boundaries between phases, i.e., at surfaces or interfaces. A detailed understanding of the elementary processes at surfaces and interfaces is therefore necessary to support and to advance the high technology that very much founds the prosperity and life style of our society. One of the challenges of modern surface science is thus to expand its range of investigations to all types of surfaces and interfaces and to develop a thorough understanding of the relationships between molecular-scale surface properties and parameters relevant to potential applications and devices.
Beyond these technological drivers, however, is a rich range of novel and fundamental physical and chemical properties at surfaces and interfaces down to the nanoscale whose study represents outstanding intellectual challenges. The current research focuses on atomic- and molecular-level studies of the structure (atomic and electronic), bonding, reactivity, dynamics, restructuring, and magnetism at the surfaces and interfaces of metals, oxides, semiconductors, polymers, biological molecules, and liquids. Such investigations are becoming more and more important in view of the increasing emphasis on nanometer-scale structures in almost every technological application, from heterogeneous catalysis to microcircuit fabrication to magnetic data storage. As the scale of devices continues to be reduced, the distinction between bulk and surface properties becomes blurred, and all of the properties of materials tend to become interfacial
This Focus Issue includes exciting new developments in the field of surface and interface science ranging, e.g., from the properties of metal-water interfaces to single-atom contacts. Special emphasis was taken to coupling theory with experiments aimed at elucidating fundamental atomic scale phenomena. It combines a broad expert and frontiers survey of research in this field today with an up to date look into the future.
