Control of octahedral rotations via octahedral connectivity in an epitaxially strained [1 u.c.//4 u.c.] LaNiO3/LaGaO3 superlattice
Media New York 2016 ABSTRACT For ABO3 perovskites, the magnetic and electronic properties couple strongly to the BO6 octahedral rotations and distortions. Therefore, precise control of the octahedral rotations and distortions via epitaxial strain and interfacial octahedral connectivity has become the key for engineering novel functionalities in ABO3 heterostructures and superlattices. In this p...
متن کاملControlling Octahedral Rotations in a Perovskite via Strain Doping
The perovskite unit cell is the fundamental building block of many functional materials. The manipulation of this crystal structure is known to be of central importance to controlling many technologically promising phenomena related to superconductivity, multiferroicity, mangetoresistivity, and photovoltaics. The broad range of properties that this structure can exhibit is in part due to the ce...
متن کاملLocal octahedral rotations and octahedral connectivity in epitaxially strained LaNiO3/LaGaO3 superlattices
For ABO3 perovskites, octahedral rotations and distortions couple strongly to the functional properties. However, in short period perovskite superlattices, the characterization of the octahedral behavior remains challenging due to the local structural variations of the BO6 octahedra. By aberration-corrected high-resolution transmission electron microscopy, we investigated the local octahedral r...
متن کاملElectrically driven octahedral rotations in SrTiO3 and PbTiO3
We investigate the oxygen octahedral rotations that occur in two perovskites, SrTiO3 and PbTiO3, as a function of applied three-dimensional electric displacement field, allowing us to map out the phase diagram of rotations in both the paraelectric and ferroelectric regions of the polar response. First-principles calculations at fixed electric displacement field are used to extract parameters of...
متن کاملThe evolution of octahedral rotations of orthorhombic LaVO3 in superlattices with cubic SrVO3
We have studied the octahedral rotations in LaVO3/SrVO3 superlattices, keeping the thickness of the orthorhombic LaVO3 layers constant and increasing the thickness of cubic SrVO3 layers. We have found that for a small thickness of SrVO3, the octahedral rotations in LaVO3 are maintained, while for an increasing thickness, these rotations are suppressed. This observation cannot be explained by pu...
