Abstract
Using a combination of chemical etching and thermal annealing methods, we have obtained atomically flat TiO 2-terminated SrTiO 2(001) with large terraces. The average width of the terrace is only determined by miscut angles. When we continuously grow tens of SrTiO 3 monolayers on such a surface under pulsed Jaser ablation deposition condition at 621°C, the growth proceeds in a layer-by-layer mode characterized by un-damped oscillations of the specular RHEED intensity. After the growth of 180 monolayers, the surface morphology is restored to the pre-growth condition with similarly large terraces after annealing in vacuum for only 30 min, indicating efficient mass transfer on TiO 2-terminated terraces.
