Vacancies in Homoepitaxially-Grown Ag and Cu films

  • Cristian E. Botez (a1), William C. Elliott (a1), Paul F. Miceli (a1) and Peter W. Stephens (a2)


X-ray scattering experiments on the homoepitaxial growth of Ag(001) Ag(111) and Cu(001) show that high vacancy concentrations can be achieved during low temperature deposition. It is observed that the vacancies, which can attain concentrations on the order of 2%, extend throughout the thickness of the deposited film. Moreover, vacancies are found to have a profound effect on the evolving morphology of certain surfaces, which is discussed in terms of prior studies of kinetic roughening in these systems.
