X-ray Absorption Linear Dichroism at the Ti K-edge of TiO2 anatase single crystals
T. C. Rossi, D. Grolimund, M. Nachtegaal +9
Anatase TiO2 (a-TiO2) exhibits a strong X-ray absorption linear dichroism with the X-ray incidence angle in the pre-edge, the XANES and the EXAFS at the titanium K-edge. In the pre…
