APS/123-QED A survey of fractured SrTiO$_{3}$ surfaces: from the micro-meter to nano-meter scale TeYu Chien $^{1}$, ∗ Nathan P. Guisinger $^{2}$, and John W. Freeland1 $^{1}$Advanced Photon Source, Argonne National Laboratory, Argonne, IL 60439 $^{2}$Center for Nanoscale Materials, Argonne National Laboratory, Argonne, IL 60439 (Dated: December 4, 2018) Cross-sectional scanning tunneling microscopy was utilized to study fractured perovskie oxide surfaces. It was found for the non-cleavable perovskite oxide, SrTiO 3 , that atomically flat terraces could be routinely created with a controlled fracturing procedure. Optical and scanning electron microscopy as well as a profilometer were used to obtain the information from sub-millimeter to sub-micrometer scales of the fractured surface topography.
