Highly Transparent and Conductive Indium-Free Vanadates Crystallized at Reduced Temperature on Glass Using a 2D Transparent Nanosheet Seed Layer

par HADRI Fouzia - publié le , mis à jour le

Indium-tin-oxide (ITO) is a widely employed transparent conducting oxide (TCO), but the indium scarcity and price encourage developing some alternatives.
The correlated metals CaVO3 and SrVO3 have been recently identifiedas new TCOs with functional properties being comparable to ITO. However,
their technological potential is limited by the critical requirement of a perovskite structure of the film, impossible to achieve via direct growth on
substrates commonly used for applications. In this article, the authors tackle this limitation by demonstrating the crystalline growth of vanadate TCOs on
glass at temperatures below 600 °C, with the help of 2D nanosheets as transparent seed layers. The functional properties do not suffer from the textured
structure of the films, as confirmed by an in-depth spectroscopic ellipsometry study, allowing for an industrially viable approach to integrate vanadate TCOs
on virtually any surface and to exploit their promising performances as a new generation TCO.
