Abstract

The surface atomic layer of c-axis oriented RBa₂Cu₃O_y (R equals Nd, Y) thin films deposited by laser ablation process and SrTiO₃ (001) single crystal has been studied by using the method of glancing incidence-exit x-ray diffuse scattering (GIEXS). Utilizing the GIEXS we have correctly identified the topmost layer of SrTiO₃ (001) single crystal with a well defined surface terminating layer. It demonstrated the effectiveness of GIEXS to distinguish the surface atomic layer from its underlying layered bulk crystal. The observations on the RBa₂Cu₃O_y thin films using GIEXS proved that the surface of NdBa₂Cu₃O_y thin films is predominantly terminated with a CuO chain plane, while a different layer covered the surface of YBa₂Cu₃O_y thin films. The results on the surface of SrTiO₃ (001) single crystal indicated that the surface termination layer of SrTiO₃ treated by the chemical method was TiO₂ plane, while the annealed SrTiO₃ surface was mainly terminated with TiO₂ plane with a small portion covered by SrO plane.
