Characterization of anatase thin films with electron and ion based methods
EMSL Project ID
1559
Abstract
There has been very much interest in titanium dioxide materials due, in part, to their important catalytic and photocatalytic properties. Rutile is the polymorph that has received the most attention in the surface science literature because of the wide availability of single crystals. However, the anatase polymorph is the more catalytically relevant phase for numerous reactions. Anatase single crystal thin films, on SrTiO3(001) substrates, grown by Oxide Metalorganic Chemical Vapor Deposition (MOCVD) System at EMSL will be investigated by x-ray photoelectron diffraction at the University of Zurich, and mass-spectrosocpy of recoiled ions using the Low Energy Ion Scattering and Direct Recoil Spectroscopy (LEIS-DRS) System at EMSL. Very little is know about the surface structure of anatase materials and these investigations should provide information related to the unique chemistries observed. Both the EMSL MOCVD and LEIS-DRS systems are the only available which can grow and characterize these materials with the respective techniques.
