The physics of Czochralski crystal growth

Abstract

The geometric configuration of the atoms in the surface of a solid is correlated with their valence electronic properties and thereby also with their chemical reactivity towards molecules interacting from the gas phase. Several aspects of these interactions are briefly reviewed: The atomic structure of clean single crystal surfaces and their changes by bond formation (chemisorption), the formation of chemisorbed phases with long-range order and associated phase transitions, the dynamics of the gas-surface interaction processes, as well as temporal oscillations in a catalytic reaction coupled to periodic structural transformations of a surface.
