Origin of metallicity of LaTiO3 ÕSrTiO3 heterostructures
It is shown that LaTiO3, in superlattices with SrTiO3, is a strongly correlated metal rather than a Mott insulator. The tetragonal lattice geometry imposed by the SrTiO3 substrate leads to an increase of the Ti 3dt2g bandwidth and a reversal of the t2g crystal field relative to the orthorhombic bulk geometry. Using dynamical mean field theory based on finite-temperature multiband exact diagonal...
متن کاملInterface Fermi States of LaAlO 3 / SrTiO 3 and Related Heterostructures CANCELLIERI , Claudia
The interfaces of LaAlO3/SrTiO3 and (LaAlO3)x(SrTiO3)1−x/SrTiO3 heterostructures have been investigated by soft x-ray photoelectron spectroscopy for different layer thicknesses across the insulator-to-metal interface transition. The valence band and Fermi edge were probed using resonant photoemission across the Ti L2,3 absorption edge. The presence of a Fermi-edge signal originating from the pa...
متن کاملGrowth control of oxygen stoichiometry in homoepitaxial SrTiO3 films by pulsed laser epitaxy in high vacuum.
In many transition metal oxides, oxygen stoichiometry is one of the most critical parameters that plays a key role in determining the structural, physical, optical, and electrochemical properties of the material. However, controlling the growth to obtain high quality single crystal films having the right oxygen stoichiometry, especially in a high vacuum environment, has been viewed as a challen...
متن کاملElectron Confinement, Orbital Ordering, and Orbital Moments in d-d Oxide Heterostructures
The (SrTiO3)m/(SrVO3)n d 0 − d multilayer system is studied with first principles methods through the observed insulator-to-metal transition with increasing thickness of the SrVO3 layer. When correlation effects with reasonable magnitude are included, crystal field splittings from the structural relaxations together with spin-orbit coupling (SOC) determines the behavior of the electronic and ma...
متن کاملSynthesis of vanadium dioxide thin films on conducting oxides and metal–insulator transition characteristics
We report on growth and physical properties of vanadium dioxide (VO2) films on model conducting oxide underlayers (Nb-doped SrTiO3 and RuO2 buffered TiO2 single crystals). The VO2 films, synthesized by rf sputtering, are highly textured as seen from X-ray diffraction. The VO2 film grown on Nb doped SrTiO3 shows over two orders of magnitude metal–insulator transition, while VO2 film on RuO2 buff...
