Sputtering of Al_2O_3 and LiNbO_3 in the electronic stopping region

Abstract

Because of recent interest in the role played by the thermal properties of materials that exhibit high energy sputtering, we have sputtered Al_2O_3 and LiNbO_3 with chlorine ions at energies between 3 MeV and 25 MeV. To detect the sputtered Al and Nb we employ thin carbon catcher foils, which are analyzed with Rutherford scattering in the forward direction. Al surface densities of 10^(14)/cm^2 and Nb surface densities of 10^(13)/cm^2 are easily measured. The sputtering yields for both Al_2O_3 and LiNbO_3 increase rapidly with increasing chlorine energy, and the Al and Nb yields are both approximately 0.2 at 20 MeV. Tests for dose, beam current, and contamination effects will be discussed.
