Abstract

The SrTiO₃(001) substrates treated by chemical etching in NH₄F-buffered HF solution and annealing in oxygen ambient have been studied by an atomic force microscopy (AFM). The SrTiO₃ substrates with TiO₂-terminated and atomically smooth surfaces and single unit cell steps have been obtained. The surface morphologies of SrTiO₃ substrates strongly depend on the treated conditions and the quality of the substrates.
