Step edge structures on the anatase TiO2 (001) surface studied by atomic-resolution TEM and STM

Research output: Contribution to journal/Conference contribution in journal/Contribution to newspaperReviewResearchpeer-review


Low-coordinate surface sites, such as those present on high-index step edges, often exhibit chemical reactivity that markedly differs from more close-packed facets. To understand the site-specific reactivity, insight into the three-dimensional atomic arrangement of step edges is needed. Here, we employ atomic-resolution transmission electron microscopy (TEM) of nanoparticles in combination with scanning tunneling microscopy (STM) of a single crystal surface to uncover the structure of prevalent step edges on the anatase TiO2 (001) surface.
