Oxide heterostructures: Atoms on the move.
Complex oxide materials are a mixture of metal and oxygen ions that exhibit a wide variety of physical functionalities1. They are among the most abundant minerals on Earth, and are of interest in many commercial technologies, from displays to electronics and communication to sensors and actuators. The multifunctional nature of these materials has opened up many possibilities for fundamental res...
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 کاملInterface Effects on Screw Dislocations in Heterostructures
The governing equation of screw dislocations in heterostructures is constructed using image method. The interface type (−1 ≤ γ ≤ 1) and distance between dislocation and interface h are considered in the new equation. The Peierls–Nabarro equations for screw dislocations in bulk and semi-infinite materials can be recovered when γ = 0 and γ = −1. The soft (γ < 0) and hard (γ > 0) interfaces can en...
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...
