Angular distributions of ions desorbing from TiO2
The dependence of the electron- and photon-stimulated desorption (ESD, PSD) O+-ion yield on surface preparation from TiO2 (110) and (001) surfaces has been studied. Angle-integrated electron-stimulated desorption yields have been measured versus annealing temperature from room temperature sputtered surfaces to 900°C annealed surfaces. Both the surface cation valence state and the surface geometry change as a function of annealing temperature, giving rise to a rich variety of ESD ion angular distribution (ESDIAD) patterns. These patterns are discussed in terms of possible models of local surface structure. © 1986.
