Step STO substrate is a atomically smooth SrTiO3 (100) with steps one unit cell in height was
obtained by treating the crystal surface with a pH-controlled NH4F-HF solution.
The homoepitaxy of SrTiO3 film on the crystal surface proceeds in a perfect layer-by-layer
mode as verified by reflection high-energy electron diffraction and atomic force microscopy. Ion scattering spectroscopy
revealed that the TiO2 atomic plane
terminated the as-treated clean surface and that the terminating atomic layer could be tuned to the SrO atomic
plane by homooepitaxial growth.
This technology provides a well-defined substrate surface for atomically regulated epitaxial growth of such perovskite oxide films
