Abstract
Pure Tb as well as TbSi1.7/Si(100) were oxidized at 600-degrees-C for 30 min at atmospheric pressure. Auger, XPS and XRD spectra of the samp les were measured before and after oxidation. The XRD results show tha t pure Th oxidizes to form TbO1.81 while the oxide layer of the oxidiz ed TbSi1.7 consists of Tb2SiO5. During sputtering of the Tb2SiO5 layer , Auger spectra show that Th and not Si is oxidized, while the XPS spe ctra show that Th as well as Si are oxidized as expected from the XRD results.
