Preparation of TiO2(110)-(1x1) surface via UHV cleavage: an scanning tunneling microscopy study.
TiO2(110) surface was successfully prepared in situ by UHV cleaving of a commercial TiO2 crystal. Scanning tunneling microscopy (STM) imaging revealed atomically flat more than 1 mum wide terraces with (110) orientation separated by steps running in [001] direction, with very low kink density. Atomically resolved STM images show periodicity in the [001] and [110] directions with the unit cell parameters measured to approximately 3 and 6.5 A, respectively, which are closed to the expected values of bulk terminated (1 x 1) surface.
