The surface structures and reactions on the single domained surfaces of SrTiO3(001) are investigated using MBE and various surface characterization techniques, such as RHEED, UPS and XPS. The selective formation of the two types of SrTiO3(001) surfaces, the TiO2 terminated and the SrO terminated surfaces, was carried out by Bi deposition/desorption cleaning method and Sr deposition, followed by oxidation in the NO2 atmosphere. It is shown that both surfaces have increased atomic distance between the first and the second layers, and the outward displacement of the first layer oxygen atoms. Surface reaction of H2O was investigated in relation to the Ti3+ defects formed by Ar+ bombardment, with the aim of obtaining knowledge on the reaction between surface functional groups and organometallic compounds at the well‐ordered surfaces.
