The morphology of the (100) surface of single-crystalline SrTiO3 was studied using frequency-modulated non-contact atomic force microscopy (FM-NCAFM) at a temperature of 100 K. After appropriate etching and heating treatments, unit-cell steps with atomically flat terraces have been successfully obtained. These surfaces were found to be quite stable under ultrahigh vacuum conditions as long as the temperature was maintained below 600 K. A specially tailored porphyrin-based molecule with carboxyphenyl substituent was dispersed on the substrates, and strong suppression of their mobility on the surface was found by FM-NCAFM observations.
