Electron 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 کاملComplex functional oxide heterostructures
This article presents a review of some salient aspects of a broad class of functional materials, namely complex oxides. These materials, exemplified by the rare earth manganites, superconducting cuprates and more recently multiferroics, are characterized by a complex crystal chemistry, that is central to competing/ cooperating spin, charge, orbital and lattice degrees of freedom. In addition to...
متن کاملOrbital engineering in symmetry-breaking polar heterostructures.
We experimentally demonstrate a novel approach to substantially modify orbital occupations and symmetries in electronically correlated oxides. In contrast to methods using strain or confinement, this orbital tuning is achieved by exploiting charge transfer and inversion symmetry breaking using atomically layered heterostructures. We illustrate the technique in the LaTiO_{3}-LaNiO_{3}-LaAlO_{3} ...
متن کاملPlaying with the geometry of oxide heterostructures
Strongly correlated electron (SCE) compounds exhibit a wide range of exotic and intellectually challenging phenomena [1], such as high-temperature superconductivity in copper oxides, colossal magnetoresistance (CMR) in manganese oxides, and the more recently unveiled, totally unexpected, superconductivity in layered iron pnictides. In these materials, novel phases are often stabilized by alteri...
متن کاملOxide heterostructures for efficient solar cells.
We propose an unexplored class of absorbing materials for high-efficiency solar cells: heterostructures of transition-metal oxides. In particular, LaVO(3) grown on SrTiO(3) has a direct band gap ∼1.1 eV in the optimal range as well as an internal potential gradient, which can greatly help to separate the photogenerated electron-hole pairs. Furthermore, oxide heterostructures afford the flexibi...
