Abstract

Lattice steps are the integral part of a surface. A lattice step can act as a diffusion barrier, an atom-trap-boundary, as well as a diffusion guide for surface atoms. The behavior of atoms at and near step edges plays an important role in epitaxial growth and surface morphology of thin films and also the dynamic behavior of the surface at elevated temperature. We will discuss how atoms move and bind at step edges, how atoms can diffuse across and along lattice steps, and how these atomic processes can affect the growth process and the structure in thin film epitaxy.
