Influence of the SrVO3 thin film thickness integrated on glass thanks to [Ca2Nb3O10]- nanosheets

• One Step Integration of SrVO 3 on glass with CNO nanosheets . • Evidence for a 2D growth mechanism of SVO on nanosheet seed layers. • Thickness effect on electron conductivity properties. • Thickness dependence of the local conductivity of SrVO 3 films determined by SSRM Scanning Probe Microscopy . Nanosheets (NS) provide an innovative method for growing perovskite thin films on diverse substrates like glass and silicon, serving as germination seeds and offering a cost-effective alternative to expensive monocrystalline substrates. According to the NS transfer process onto the substrate, more than 85–90 % of the substrate is covered. However, a small fraction of the perovskite film grows directly on the substrate. This raises several questions: Is the perovskite film grown on glass conductive? How does the NS network influence electrical properties at macroscopic and submicron scales? To address these questions, we investigated the impact of thickness on the transport properties of transparent conductive SrVO 3 vanadate deposited on glass coated with [Ca2Nb3O10]- nanosheets (CNO NS). Macroscopic measurements revealed significant degradation of transport properties at thicknesses below 15 nm. In-plane local electrical properties were examined using Scanning Spreading Resistance Microscopy. Our findings indicate that local transport remains nearly constant when SrVO 3 is grown on NS, while a strong thickness dependence is observed when SrVO 3 is directly deposited on glass. These results contribute to a better understanding of the growth process, the integration of functional oxides on NS and open new perspectives for tuning the properties of vanadate films as transparent electrodes.
