Abstract

Mixed LaAlO₃-SrTiO₃ single crystals have been grown by using flame fusion, starting from homogeneously synthesized solid-solution powders. X-ray powder diffraction of the latter show the solid-solution system to be continuous over the whole composition range. Phase boundaries were determined by means of optical and calorimetric measurements. In the composition range of 100% to 20% LaAlO₃, a cubic Pm3m to trigonal R3̄c phase boundary was observed.

Combinatorial synthesis and optical characterization of alloy and superlattice films based on SrTiO <inf>3</inf> and LaAlO <inf>3</inf>
2006, Applied Surface Science
We have grown alloy and superlattice films consisting of SrTiO₃ (STO) and LaAlO₃ (LAO) by pulsed laser deposition using composition-spread technique. All the (STO)_x(LAO)_1−x (0 ≤ x ≤ 1) alloy and superlattice films exhibited a single-phase perovskite structure. The optical properties of these films were characterized by absorption spectroscopy at room temperature. The spectra show a broad absorption due to O 2p-Ti 3d(t_2g) transition in an ultraviolet region. We found that absorption edges of both alloy and superlattice films systematically shifted to higher energy with increasing LAO composition. Clear difference was observed in the composition dependence of the indirect and a direct band edges.
Cubic phase in the La<inf>1-x</inf>Sr<inf>x</inf>AlO<inf>3-x/2</inf> system
1999, Materials Research Bulletin
A series of La_1−xSr_xAlO_3−x/2 phases were prepared from x = 0.00 to 0.35 at 1550°C in air. Rhombohedral symmetry was observed for values of x up to 0.27, but the La_0.65Sr_0.35AlO_2.725 sample appears to be cubic. Dieletric measurements on sintered pellets show the dielectric constant decreasing from about 24 to 19 with Sr substitution, whereas dielectric loss increases from 10⁻⁴ to 2.5 × 10⁻³.
Electrical conduction behavior in (La<inf>0.9</inf>Sr<inf>0.1</inf>)M<sup>III</sup>O<inf>3-δ</inf> (M<sup>III</sup> = Al, Ga, Sc, In, and Lu) perovskites
1997, Solid State Ionics
Oxide ion conduction in A³⁺B³⁺O₃-type perovskites, (La_0.9Sr_0.1)M^IIIO_3−δ (M^III=Al, Ga, Sc, In, and Lu) has been investigated as a function of crystallographic free volume (V_f), taking the distortion from `ideal' cubic structure into consideration. The Ga compound, whose V_f is ca. 13 Å³, showed the maximum conductivity of 8.1×10⁻² S cm⁻¹ (at 980°C, in N₂) and the minimum activation energy of 0.60 eV (from 730–980°C, in N₂) for oxide ion conduction. This behavior arises from the balance between an increase in V_f and a decrease in symmetry in the perovskite structure.

A new series of K₂NiF₄ related layered compounds SrLaScO₄ and SrLa₂Sc₂O₇ have been synthesized. Structural parameters were determined by X-ray powder Rietveld analysis. The results showed both compounds have orthorhombic lattice symmetry with the constants $a = 5.7657(5) A ̊$ , $b = 5.7513(4) A ̊$ and $c = 12.467(1) A ̊$ for SrLaScO₄ and a = 5.7818(5), b = 5.7367(5) and $b = 20.534(2) A ̊$ for SrLa₂Sc₂O₇. Although pure phases were not obtained for compounds BaLaScO₄ and BaLa₂Sc₂O₇, their X-ray diffraction patterns could be indexed as a tetragonal lattice symmetry, respectively. The orthorhombic nature of crystal distortion in Srcompounds at room temperature was attributed to be the tilting of ScO₆ octahedra in perovskite layer. Two types of reorientation of the octahedra occurred with increasing temperature for both SrLaScO₄ and SrLa₂Sc₂O₇, along the sequence of symmetry O' → O → T. During these transitions dielectric anomalies were observed. The anomalies are considered to be accompanied by a zone-boundary phase transition attributed to the ScO₆ octahedra rotation.
