Surface Structures of Ultrathin TiOx Films on Au(111)

Abstract:

Ultrathin films of titanium oxide were grown on (22 × - √3)-reconstructed Au(111) surfaces by Ti evaporation in ultrahigh vacuum (UHV). Following Ti deposition onto room temperature Au substrates, the samples were oxidized at 600 °C in 10-6 Pa O2. Scanning tunneling microscopy (STM) images show that three different ordered TiO x film structures form as the amount of deposited Ti is increased. Auger electron spectroscopy (AES) was used to measure the stoichiometry of the films. The first struc...
