SrTiO $_3$表面断裂的研究进展：从微米到纳米尺度
A survey of fractured SrTiO$_3$ surfaces: from the micro-meter to nano-meter scale
摘要：
利用截面扫描隧道显微镜来研究断裂的钙钛矿氧化物表面。发现对于不可裂解的钙钛矿氧化物SrTiO $_{3}$，可以用受控的断裂过程常规地产生原子级平坦的阶地。光学和扫描电子显微镜以及轮廓仪被用来获得从亚毫米到亚微米尺度的断裂表面形貌的信息。
英文摘要：
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.
