Microscopic Morphology of Gallium Clusters on GaAs(001)
Published online by Cambridge University Press: 25 February 2011
Abstract
A microscopic study of the system Ga/GaAs(001) is presented to explain the origin for different Ga cluster shapes on a single surface. The model is based on the finding that a significant fraction of the Ga clusters reaches below the GaAs surface plane and the shape of these depressions represents a minimum energy configuration if low-index planes are formed. Other metal/compound semiconductor systems may display similar shape modifications.
