(Sub)surface mobility of oxygen vacancies at the TiO${}_2$ anatase (101) surface

Philipp Scheiber, Martin Fidler, Olga Dulub +5

Anatase is a metastable polymorph of TiO${}_2$. In contrast to the more widely-studied TiO${}_2$ rutile, O vacancies (V${}_{\mathrm{O}}$'s) are not stable at the anatase (101) surface. Low-…
