Title: Role of temperature and oxygen content on structural and electrical properties of LaBaCo₂O_5+δ thin films

Abstract

Here, the role of temperature and the oxygen content in the structural transformation and electrical conductivity of epitaxial double perovskite LaBaCo₂O_5+δ (0≤ δ ≤ 1) thin films was systematically investigated. Reciprocal space mapping and ω-2θ x-ray diffraction performed at different temperatures in vacuum indicate that oxygen vacancies in the films become ordered at high temperature in a reducing environment. The changes of the oxygen content and the degree of oxygen vacancy ordering in the films result in a strong in-plane anisotropic lattice deformation and a large thermal expansion coefficient along the c-axis direction. The electrical conductivity measurements reveal that these behaviors are related to the degree of oxygen vacancy formation and lattice deformation in the films.

Electric transport coefficients in highly epitaxial LaBaCo{sub 2}O{sub 5 + δ} films with “p-to-n” transition induced by oxygen deficiency

Journal Article Shaibo, J. ; Zhang, Q. Y., E-mail: qyzhang@dlut.edu.cn ; Hu, H. C. ; ... - Journal of Applied Physics

Electric transport coefficients such as carrier type, density, and mobility are the important physical parameters in designing functional devices. In this work, we report the study on the electric transport coefficients of the highly epitaxial LaBaCo{sub 2}O{sub 5 + δ} (LBCO) films, which were discussed as a function of electric conductivity for the first time and compared with the results calculated by the theory for mixed conduction. The mobility in the LBCO films was determined to be ∼0.85 and ∼40 cm{sup 2}/V s for holes and electrons, respectively, and the density of p-type carriers strongly depends on the oxygen deficiency.

Anisotropic strain induced directional metallicity in highly epitaxial LaBaCo₂O_5.5+δ thin films on (110) NdGaO₃

Journal Article Ma, Chunrui ; Han, Dong ; Liu, Ming ; ... - Scientific Reports

Highly directional-dependent metal-insulator transition is observed in epitaxial double perovskite LaBaCo₂O_5.5+δ films. The film exhibit metallic along [100], but remain semiconducting along [010] under application of a magnetic field parallel to the surface of the film. The physical origin for the properties is identified as in-plane tensile strain arising from oxygen vacancies. First-principle calculations suggested the tensile strain drastically alters the band gap, and the vanishing gap opens up [100] conduction channels for Fermi-surface electrons. Lastly, our observation of strain-induced highly directional-dependent metal-insulator transition may open up new dimension for multifunctional devices.

Journal Article Ruiz-Zepeda, F. ; Ma, C. ; Bahena Uribe, D. ; ... - Journal of Applied Physics

A giant magnetoresistance effect (∼46% at 20 K under 7 T) and anomalous magnetic properties were found in a highly epitaxial double perovskite LaBaCo{sub 2}O{sub 5.5+δ} (LBCO) thin film on (001) MgO. Aberration-corrected Electron Microscopy and related analytical techniques were employed to understand the nature of these unusual physical properties. The as-grown film is epitaxial with the c-axis of the LBCO structure lying in the film plane and with an interface relationship given by (100){sub LBCO} || (001){sub MgO} and [001]{sub LBCO} || [100]{sub MgO} or [010]{sub MgO}.

Manipulation of Optical Transmittance by Ordered-Oxygen-Vacancy in Epitaxial LaBaCo₂O_5.5+δ Thin Films

Journal Article Cheng, Sheng ; Lu, Jiangbo ; Han, Dong ; ... - Scientific Reports

Giant optical transmittance changes of over 300% in wide wavelength range from 500 nm to 2500 nm were observed in LaBaCo₂O_5.5+δ thin films annealed in air and ethanol ambient, respectively. The reduction process induces high density of ordered oxygen vacancies and the formation of LaBaCo₂O_5.5 (δ = 0) structure evidenced by aberration-corrected transmission electron microscopy. Moreover, the first-principles calculations reveal the origin and mechanism of optical transmittance enhancement in LaBaCo₂O_5.5 (δ = 0), which exhibits quite different energy band structure compared to that of LaBaCo₂O₆ (δ = 0.5). The discrepancy of energy band structure was thought to be the directmore »« less

Journal Article Wu, Xuewang ; Walter, Jeff ; Feng, Tianli ; ... - Advanced Functional Materials

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 limitmore »« less
