Formation and Etching of the Insulating Sr‐Rich V<sup>5+</sup> Phase at the Metallic SrVO<sub>3</sub> Surface Revealed by Operando XAS Spectroscopy Characterizations
Abstract
<jats:title>Abstract</jats:title><jats:p>In the search of low cost and more efficient electronic devices, here the properties of SrVO<jats:sub>3</jats:sub> transparent conductor oxide (TCO) thin film are investigated, both visible‐range optically transparent and highly conductive, it stands as a promising candidate to substitute the standard indium‐tin‐oxide (ITO) in applications. Its surface stability under water (both liquid and vapor) and other gaseous atmospheres is especially addressed. Through the use of spectroscopy characterizations, X‐ray photoemission and operando X‐ray absorption measurements, the formation of a thin Sr‐rich V<jats:sup>5+</jats:sup> layer located at the surface of the polycrystalline SrVO<jats:sub>3</jats:sub> film with aging is observed, and for the first time how it can be removed from the surface by solvating in water atmosphere. The surface recovery is associated to an etching process, here spectroscopically characterized in operando conditions, allowing to follow the stoichiometric modification under reaction. Once exposed in oxygen atmosphere, the Sr‐rich V<jats:sup>5+</jats:sup> layer forms again. The findings improve the understanding of aging effects in perovskite oxides, allowing for the development of functionalized films in which it is possible to control or to avoid an insulating surface layer. This constitutes an important step towards the large‐scale use of V‐based TCOs, with possible implementations in oxide‐based electronics.</jats:p>
