Abstract
Abstract Auger electron spectroscopy using excitation by grazing impact of protons and by impact of electrons was applied to determine the elemental composition of the topmost and near-surface layers of DyScO 3 (110). The vicinal DyScO 3 crystals were annealed at 1320 K in O 2 and Ar atmospheres by varying annealing time. The prepared surfaces show regularly arranged, smooth terraces with single-atomic steps. The surfaces have DyO termination after annealing in oxygen flow for 30–60 min. Annealing for 600 min of DyScO 3 in oxidizing or inert atmospheres resulted in a ScO x termination.
