We have prepared rutile TiO2(110) surfaces that are atomically flat over large areas as shown by scanning tunneling microscopy (STM). We have obtained atomic resolution images of TiO2(110) where the (1×1) structure is found to cover all of the observed areas on the sample. In some cases, we also observe an elongated defect structure oriented along the  direction. We discuss geometric and electronic properties of models for the clean and defective surfaces which can be used to explain the observed STM images.
