Oxygen Evolution Reaction on Perovskites: A Multieffect Descriptor Study Combining Experimental and Theoretical Methods
Xi Cheng, Emiliana Fabbri, Yuya Yamashita +6
The correlation between ex situ electronic conductivity, oxygen vacancy content, flat-band potential (Efb), and the oxygen evolution reaction (OER) activity for a wide range of per…
Control of surface potential at polar domain walls in a nonpolar oxide
G. F. Nataf, M. Guennou, J. Kreisel +8
Ferroic domain walls could play an important role in microelectronics, given their nanometric size and often distinct functional properties. Until now, devices and device concepts…
Surface phase transitions in BiFeO3 below room temperature
R. Jarrier, X. Marti, J. Herrero-Albillos +15
We combine a wide variety of experimental techniques to analyze two heretofore mysterious phase transitions in multiferroic bismuth ferrite at low temperature. Raman spectroscopy,…
High-pressure phase transitions in BiFeO3: hydrostatic vs. non-hydrostatic conditions
Mael Guennou, Pierre Bouvier, Raphaël Haumont +2
We report high-pressure x-ray diffraction experiments on BiFeO3 (BFO) single crystals in diamond-anvil cells up to 14 GPa. Two data sets are compared, one in hydrostatic conditions…
High-pressure investigations of CaTiO3 up to 60 GPa using X-ray diffraction and Raman spectroscopy
Mael Guennou, Pierre Bouvier, Benjamin Krikler +3
In this work, we investigate calcium titanate (CaTiO3 - CTO) using X-ray diffraction and Raman spectroscopy up to 60 and 55 GPa respectively. Both experiments show that the orthorh…
Effect of high pressure on multiferroic BiFeO3
R. Haumont, P. Bouvier, A. Pashkin +6
We report experimental evidence for pressure instabilities in the model multiferroic BiFeO3 and namely reveal two structural phase transitions around 3 GPa and 10 GPa by using diff…
