Title: Band alignment and electrocatalytic activity at the p-n La_0.88Sr_0.12FeO₃/SrTiO₃ (001) heterojunction

Abstract

Ferrites perovskites have exhibited promising p-type conductivity and oxygen evolution reaction (OER) activity. In this work, we investigate heteroepitaxial p-n junctions formed with La_0.88Sr_0.12FeO₃ and n-SrTiO₃(001). Sr substitution for La in LaFeO₃ is shown to be effective for introducing p-type conductivity, lowering the optical bandgap, and enhancing electrocatalytic OER. A staggered, type-II band alignment with a large built-in potential within the LSFO forms due to the polar interface. This electronic structure facilitates charge transfer across the p-n junction and accounts for the strongly thickness-dependent extent of OER we observe.

Optical absorption in epitaxial La{sub 1-x}Sr{sub x}FeO{sub 3} thin films

Journal Article Scafetta, M D. ; Xie, Y. J. ; Torres, M. ; ... - Applied Physics Letters

We report the dependence of optical absorption on Sr concentration in La{sub 1-x}Sr{sub x}FeO{sub 3} (LSFO) (x{<=}0.4) perovskite thin films. Strained epitaxial films were deposited on SrTiO{sub 3} substrates using oxide molecular beam epitaxy. We find systematic changes in the optical absorption spectra with increasing x including a red-shift of transition energies and the increasing presence of a lower energy transition within the fundamental gap of pure LaFeO{sub 3}. These results serve as a demonstration of the complex manner in which absorption spectra can be altered in complex oxides via heterovalent A-site substitution.

Quantitative phase separation in multiferroic Bi{sub 0.88}Sm{sub 0.12}FeO{sub 3} ceramics via piezoresponse force microscopy

Journal Article Alikin, D. O., E-mail: enis.alikin@urfu.ru ; Turygin, A. P. ; Shur, V. Ya. ; ... - Journal of Applied Physics

BiFeO{sub 3} (BFO) is a classical multiferroic material with both ferroelectric and magnetic ordering at room temperature. Doping of this material with rare-earth oxides was found to be an efficient way to enhance the otherwise low piezoelectric response of unmodified BFO ceramics. In this work, we studied two types of bulk Sm-modified BFO ceramics with compositions close to the morphotropic phase boundary (MPB) prepared by different solid-state processing methods. In both samples, coexistence of polar R3c and antipolar P{sub bam} phases was detected by conventional X-ray diffraction (XRD); the non-polar P{sub nma} or P{sub bnm} phase also has potential tomore »« less

Journal Article Tank, Tejas M., E-mail: tejas.physics2020@gmail.com ; Sanyal, Sankar P. ; Mukovskii, Ya. M. - AIP Conference Proceedings

We have investigated electrical-transport, magneto-transport, magnetic and thermal properties of the hole doped La{sub 0.7}Ca{sub 0.24}Sr{sub 0.06}MnO{sub 3} (LCSMO) and La{sub 0.88}Ca{sub 0.12}MnO{sub 3} (LCMO) single crystals, prepared using floating zone technique. The crystallographic direction dependence of metal to insulator transition (T{sub P}) occurs at 290 K along c-axis and T{sub P} = 280 K along ab-plane for LCSMO single crystal, while no electronic transition was observed over the whole temperature range under the magnetic field at 8 T for LCMO single crystal. Resistivity study shows that the T{sub P} is higher along the c-axis as compared to that in the ab-plane,more »« less

Superlattice-induced ferroelectricity in charge-ordered La _1/3 Sr _2/3 FeO ₃

Journal Article Park, Se Young ; Rabe, Karin M. ; Neaton, Jeffrey B. - Proceedings of the National Academy of Sciences of the United States of America

Charge-order–driven ferroelectrics are an emerging class of functional materials, distinct from conventional ferroelectrics, where electron-dominated switching can occur at high frequency. Despite their promise, only a few systems exhibiting this behavior have been experimentally realized thus far, motivating the need for new materials. In this work, we use density-functional theory to study the effect of artificial structuring on mixed-valence solid-solution La1/3Sr2/3FeO3 (LSFO), a system well studied experimentally. Our calculations show that A-site cation (111)-layered LSFO exhibits a ferroelectric charge-ordered phase in which inversion symmetry is broken by changing the registry of the charge order with respect to the superlattice layering.more »« less
