摘要

Upon sputtering and annealing in UHV at ~1000 K, the rutile TiO_2(110) surface undergoes a 1 X 1 → 1 X 2 phase transition. The resulting 1 X 2 surface is Ti rich, formed by strands of double Ti rows as seen on scanning tunneling microscopic images, but its detailed structure and composition have been subject to debate in the literature for years. Recently, Park et al. [Phys. Rev. Lett. 96, 226105 (2006)] have proposed a model where Ti atoms are located on interstitial sites with Ti_2O stoichiometry. This model, when it is analyzed using LEED-Ⅳ data [Phys. Rev. Lett. 96, 0055502 (2006)], does not yield an agreement between theory and experiment as good as the previous best fit for Onishi and Iwasawa's model for the long-range 1 X 2 reconstruction. Therefore, the Ti_2O_3 added row is the preferred one from the point of view low-energy electron diffraction.
