Formation of well-defined MgO layers

Oxide layers of approximately 10 Å in thickness have been formed in several laboratories by exposure of the Mg(0001) surface to oxygen exposures of 100 Langmuirs or less. Although there is good agreement of the oxygen uptake profiles in these studies, the structure and composition of these films are sensitive to the order of the metal surface and to the conditions of film growth. We review here the physical properties of MgO films as probed by spectroscopic techniques, and the application of these materials as models of the surface of bulk MgO. Studies of the chemical properties of oxide films may lead to identification of the active sites on bulk oxides, as well as providing information, complementing that from spectroscopic techniques, useful for characterizing the films themselves. © 1988.
