The -axis dimer and its electronic break-up: the insulator-to-metal transition in TiO
C. F. Chang, T. C. Koethe, Z. Hu +17
We report on our investigation of the electronic structure of TiO using (hard) x-ray photoelectron and soft x-ray absorption spectroscopy. From the distinct satellite struc…
Spin-orbital excitation continuum and anomalous electron-phonon interaction in the Mott insulator LaTiO
C. Ulrich, G. Khaliullin, M. Guennou +3
Raman scattering experiments on stoichiometric, Mott-insulating LaTiO over a wide range of excitation energies reveal a broad electronic continuum which is featureless in the p…
Elemental Topological Insulator with a Tunable Fermi Level: Strained α-Sn on InSb(001)
A. Barfuss, L. Dudy, M. R. Scholz +16
We report on the epitaxial fabrication and electronic properties of a topological phase in strained α-Sn on InSb. The topological surface state forms in the presence of an unusual…
Momentum dependence of orbital excitations in Mott-insulating titanates
C. Ulrich, L. J. P. Ament, G. Ghiringhelli +9
High-resolution resonant inelastic x-ray scattering has been used to determine the momentum dependence of orbital excitations in Mott-insulating LaTiO and YTiO over a wide…
Magnetoelastic coupling in RETiO3 (RE = La, Nd, Sm, Gd, Y)
A. C. Komarek, H. Roth, M. Cwik +6
A detailed analysis of the crystal structure in RETiO3 with RE = La, Nd, Sm, Gd, and Y reveals an intrinsic coupling between orbital degrees of freedom and the lattice which cannot…
Mott-Hubbard exciton in the optical conductivity of YTiO3 and SmTiO3
A. Gössling, R. Schmitz, H. Roth +5
In the Mott-Hubbard insulators YTiO3 and SmTiO3 we study optical excitations from the lower to the upper Hubbard band, d^1d^1 -> d^0d^2. The multi-peak structure observed in the op…
