Abstract
The reconstructed anatase TiO2(001) surface has been investigated by low energy electron diffraction (LEED) and angle-resolved mass-spectroscopy of recoiled ions (AR-MSRI). Prior experimental and theoretical investigations have only observed or considered a (1x1) unreconstructed termination for this surface with no detailed structural analysis. Our LEED results indicate a previously unobserved two-domain (1x4) reconstruction after sputtering and annealing the (1x1) surface. Simulations of the A-MSRI experimantal data indicate a best fit for a surface that is microfaceted, revealing both (103) and (103) surface planes.
