Single-Crystal Epitaxial Thin Films of the Isotropic Metallic Oxides Sr _{1– x} Ca _x RuO ₃ (0 ≤ × ≤ 1)

Abstract

Single-crystal epitaxial thin films of the isotropic metallic oxides Sr1-xCaxRuO(3) (0 </= x </= 1) were grown on miscut SrTiO(3)(100) substrates in situ by 90 degrees off-axis sputtering. These thin films exhibit low isotropic resistivities, excellent chemical and thermal stability, good surface smoothness, and high crystalline quality. Furthermore, the lattice parameters and magnetic properties can be varied by simply changing the strontium/calcium ratio. These epitaxial thin films, and their multilayer structures with other oxide materials, can be used for the fabrication of superconducting, ferroelectric, magneto-optic, and electro-optic devices.

Solution‐Grown Monocrystalline Hybrid Perovskite Films for Hole‐Transporter‐Free Solar Cells

“…As a qualitative indication of crystallinity, this value is comparable to those of high-quality epitaxial perovskite oxide films. [16,24] Notably, it is also smaller than that of bulk MAPbBr 3 perovskite crystals (FWHM=0.044°, Figure 2d), which suggests that the cavitation process, though as an external disturbance, does not deteriorate crystallinity. The high quality of the monocrystalline films was further corroborated by the space-charge limited current measurement, showing a low trap density of ~10 11 cm -3 ( Figure S4, Supporting Information).…”

“…intercalation of volatile and vulnerable organic components with a brittle inorganic framework, makes their monocrystalline films difficult to be achieved by deposition techniques that are wellestablished for inorganic compounds (e.g., pulsed laser deposition and sputtering) and organic materials (e.g., vapor growth). [15][16][17] We were thus motivated to grow hybrid perovskite monocrystalline films on substrates by exploiting the perovskite's propensity to crystallize in solution. However, simple solutionbased techniques that crystallize perovskites from saturated precursor solutions produce only free-standing bulk crystals with small aspect ratios.…”

“…On the other hand, it is nowadays possible to grow high quality epitaxial films of SrRuO 3 and Sr 1−x Ca x RuO 3 [16]. In the present article, we study the anomalous Hall resistivity of epitaxial films of Sr 1−x Ca x RuO 3 (0 ≤ x ≤ 0.4), and its evolution as the ferromagnetic interaction decreases with x.…”
