This book is the first to give a comprehensive account of the fundamental properties of metal-oxide surfaces and their interaction with atoms, molecules and overlayers. The surfaces of metal oxides play a crucial role in an extremely wide range of phenomena, including the environmental degradation of high-Tc superconductors and catalysis. They are also increasingly important in processes such as the passivation of metal surfaces and gas sensing for pollution monitoring and control. As well as giving a general overview of the properties of metal-oxides, an extensive and thorough compilation of the research that has been performed on well characterised oxide surfaces is provided, thus making the book suitable for those graduate students and established researchers in materials science, chemistry or physics who have an interest in metal-oxide surfaces.
