Abstract

Density Functional Theory and X-ray standing wave atomic imaging are combined to develop models of platinum overlayers, patches and small particles on (001) surfaces of SrTiO3. The higher coverage (0.3 ML nominal Pt) experimental result matches best to a simple 1 × 1 surface model. For lower coverage (0.1 ML) a Ti deficient TiO2 double layer termination is identified as most favorable. A simple model is developed by which XSW amplitudes can be used to infer the aspect ratio of surface structures.
