TiO2(110) surface was successfully prepared in-situ by UHV cleaving of a commercial TiO2 crystal.. STM imaging revealed atomically flat more than 1 ?m 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 [ ] directions with the unit cell parameters measured to ~3 Å and 6.5 Å respectively which are closed to the expected values of bulk terminated (1x1) surface.
