| Summary: | The origin of the improved performance of erbium-doped TiO2 film via the hydrothermal doping process is
discussed. Facet engineering of rutile TiO2 on the surface atomic structure is known but the electronic structure
has been rarely studied to date. Particularly, the dominant facet of rutile TiO2 has changed upon doping resulting
with co-exposed {101}/{111} facet as shown in TEM results. The surface energy levels of the conduction band
(CB) and valence band (VB) on different crystal surfaces change, and these variations in energy levels will cause
the electrons and holes to gravitate toward different crystal faces and inhibit the electron-hole recombination. |
