Structural stability and formability of ABO3-type perovskite compounds.
On the basis of the bond-valence model (BVM) and structure-map technology, the structural stability and formability of ABO(3)-type perovskite compounds were investigated in 376 ABO(3)-type compounds. A new criterion of structural stability for ABO(3)-type perovskite compounds has been established by the bond-valence calculated tolerance factors, which are in the range 0.822-1.139. All global in...
متن کاملImpact of interfacial coupling of oxygen octahedra on ferromagnetic order in La0.7Sr0.3MnO3/SrTiO3 heterostructures
La0.7Sr0.3MnO3, a half-metallic ferromagnet with full spin polarization, is generally used as a standard spin injector in heterostructures. However, the magnetism of La0.7Sr0.3MnO3 is strongly modified near interfaces, which was addressed as "dead-layer" phenomenon whose origin is still controversial. Here, both magnetic and structural properties of La0.7Sr0.3MnO3/SrTiO3 heterostructures were i...

متن کاملPreparation and Properties of Thin Film Materials with Perovskite Type Structure (mixed Oxides Abo3)
Barium Titanate (BaTiO3) and Lithium Niobate (LiNb03) thin films (0,2 to 1 pm) were deposited ont0 Platinum foils and Silicon wafers (M. 1. S. capacitor structure). In the present work, polycristalline films which had been prepared by R. F. cathodic sputtering of ceramic targets were studied. With a substrate temperature below 300 OC during the deposition, good insulating amorphous films with a...
متن کاملInterfacial Kinetics of Efficient Perovskite Solar Cells
Perovskite solar cells (PSCs) have immense potential for high power conversion efficiency with an ease of fabrication procedure. The fundamental understanding of interfacial kinetics in PSCs is crucial for further improving of their photovoltaic performance. Herein we use the current-voltage (J-V) characteristics and impedance spectroscopy (IS) measurements to probe the interfacial kinetics on ...
