| dc.description.abstract | We report spectroscopic ellipsometry measurements of the anisotropy of the interband transitions parallel and perpendicular to the planes of (LaTiO3)n(LaAlO3)5 multilayers with n = 1-3. These provide direct information about the electronic structure of the two-dimensional (2D) 3d(1) state of the Ti ions. In combination with local density approximation, including a Hubbard U calculation, we suggest that 2D confinement in the TiO2 slabs lifts the degeneracy of the t(2g) states leaving only the planar d(xy) orbitals occupied. We outline that these multilayers can serve as a model system for the study of the t(2g) 2D Hubbard model. | - |
