Abstract

Abstract : Ultrathin films of TiO2 were grown on a W(100)–O(2 × 1) substrate and characterised with a combination of scanning tunneling microscopy (STM) and low energy electron diffraction. In addition to islands of rutile TiO2 (110) with (1 × 1) termination that were reported previously, we also observed rutile TiO2 (110) islands with a (1 × 2) film termination. A lepidocrocite-like TiO2 nanosheet was also observed on the W(100) surface. High resolution STM images show that the nanosheet grows in the principal orthogonal directions of the W(100) substrate and forms a commensurate (1 × 7) coincident cell.
