Title: Glass-Like Through-Plane Thermal Conductivity Induced by Oxygen Vacancies in Nanoscale Epitaxial La_0.5Sr_0.5CoO_3–_δ [Glass-Like Thermal Conductivity Induced by Oxygen Vacancies in Nanoscale Epitaxial La_0.5Sr_0.5CoO_3–_δ]

Abstract

Here, ultrafast time-domain thermoreflectance (TDTR) is utilized to extract the through-plane thermal conductivity (Λ_LSCO) of epitaxial La_0.5Sr_0.5CoO_3–δ (LSCO) of varying thickness (<20 nm) on LaAlO₃ and SrTiO₃ substrates. These LSCO films possess ordered oxygen vacancies as the primary means of lattice mismatch accommodation with the substrate, which induces compressive/tensile strain and thus controls the orientation of the oxygen vacancy ordering (OVO). TDTR results demonstrate that the room-temperature Λ_LSCO of LSCO on both substrates (1.7 W m^–1 K^–1) are nearly a factor of four lower than that of bulk single-crystal LSCO (6.2 W m^–1 K^–1). Remarkably, this approaches the lower limit of amorphous oxides (e.g., 1.3 W m^–1 K^–1 for glass), with no dependence on the OVO orientation. Through theoretical simulations, origins of the glass-like thermal conductivity of LSCO are revealed as a combined effect resulting from oxygen vacancies (the dominant factor), Sr substitution, size effects, and the weak electron/phonon coupling within the LSCO film. The absence of OVO dependence in the measured Λ_LSCO is rationalized by two main effects: (1) the nearly isotropic phononic thermal conductivity resulting from the imperfect OVO planes when δ is small; (2) the missing electronic contribution to Λ_LSCO along the through-plane direction for these ultrathinmore » LSCO films on insulating substrates.« less

Stretching Epitaxial La_0.6Sr_0.4CoO_3–δ for Fast Oxygen Reduction

Journal Article Lee, Dongkyu ; Jacobs, Ryan ; Jee, Youngseok ; ... - Journal of Physical Chemistry. C

The slow kinetics of the oxygen reduction reaction (ORR) is one of the key challenges in developing high performance energy devices, such as solid oxide fuel cells. Straining a film by growing on a lattice-mismatched substrate has been a conventional approach to enhance the ORR activity. However, due to the limited choice of electrolyte substrates to alter the degree of strain, a systematic study in various materials has been a challenge. Here, we explore the strain modulation of the ORR kinetics by growing epitaxial La_0.6Sr_0.4CoO_3-δ (LSCO) films on yttria-stabilized zirconia substrates with the film thickness below and above the criticalmore »« less

Temporal and thermal evolutions of surface Sr-segregation in pristine and atomic layer deposition modified La_0.6Sr_0.4CoO_3-δ epitaxial films

Journal Article Wen, Yeting ; Yang, Tianrang ; Lee, Dongkyu ; ... - Journal of Materials Chemistry. A

The bulk-to-surface Sr segregation can seriously compromise the stability of oxygen electrocatalysis in La_1-xSr_xCoO_3-δ and limit its practical applications such as in solid oxide fuel cells. In this work, we show via in situ ambient pressure X-ray photoelectron spectroscopy (APXPS) that the surface Sr-segregation is a kinetically fast process and the equilibrium surface Sr-concentration follows Arrhenius law from 250 to 520 °C at a fixed p_O₂ = 1 × 10^-3 atm. Furthermore, we also show that application of a nanoscaled, atomic layer deposition (ALD) derived ZrO₂ overcoat can effectively suppress the Sr-segregation by reducing the surface concentration of oxygen vacancies.more »« less

Journal Article Xinhua, Zhu ; Chan, H L.-W. ; Choy, C -L ; ... - Journal of Applied Physics

Compositionally-graded (Ba{sub 1-x}Sr{sub x})TiO{sub 3} (BST) epitaxial thin films (with x decreasing from 0.25 to 0.0) were deposited by pulsed laser deposition on (100)LaAlO{sub 3} (LAO) single-crystal substrates covered with a conductive La{sub 0.5}Sr{sub 0.5}CoO{sub 3} (LSCO) layer as a bottom electrode. X-ray and electron diffraction patterns demonstrate that the entire graded film has a single-crystal cubic structure. The epitaxial relationship between BST, LSCO, and LAO can be described as (100){sub BST} parallel (100){sub LSCO} parallel (100){sub LAO}; [001]{sub BST} parallel [001]{sub LSCO} parallel [001]{sub LAO}.

Effect of in-plane epitaxy on magnetotransport properties of (La{sub 0.5}Sr{sub 0.5})CoO{sub 3} thin films

Journal Article Kwon, C ; Gim, Y ; Fan, Y ; ... - Applied Physics Letters

We have systematically studied the temperature- and magnetic field-dependent resistance in (La{sub 0.5}Sr{sub 0.5})CoO{sub 3} (LSCO) films with various degrees of in-plane texturing using the biaxially oriented LSCO on CeO{sub 2}/YSZ/SiO{sub 2}/Si substrates. We find that the ferromagnetic transition temperature, T{sub c}, is much the same in all samples while the resistive transition exhibits metallic behavior (dR/dT{gt}0) in the epitaxial LSCO to semiconducting behavior (dR/dT{lt}0) in the poorly textured LSCO. The magnetoresistance (MR) in the epitaxial LSCO on a LaAlO{sub 3} substrate displays two distinct regions; the low field hysteretic MR related to the magnetization hysteresis and the high fieldmore »« less
