Quest for a pristine unreconstructed SrTiO3(001) surface: An atomically resolved study via noncontact atomic force microscopy
Original language description
The surfaces of perovskite oxides affect their functional properties, and while a bulk-truncated (1 x 1) termination is generally assumed, its existence and stability is controversial. Here, such a surface is created by cleaving the prototypical SrTiO3 (001) in ultrahigh vacuum, and its response to thermal annealing is observed. Atomically resolved noncontact atomic force microscopy (nc-AFM) shows that intrinsic point defects on the as-cleaved surface migrate at temperatures above 200 degrees C. At 400 degrees C-500 degrees C, a disordered surface layer forms, albeit still with a (1 x 1) pattern in low-energy electron diffraction (LEED). Purely TiO2 -terminated surfaces, prepared by wet-chemical treatment, are also disordered despite their (1 x 1) periodicity in LEED.
