The transition to organic electronics requires new devices on the nanometer scale composed only by organic materials, providing small, flexible, transparent and cheap devices. Among electronic devices, the spin valves have stood out for their rapid transfer from the experimental phase to the general public products, but a reliable organic spin valve nanometric device is yet to be developed.
The scientific objective of this project is to fill that gap. By using advanced, industrially scalable nanotechnology methods, we intend to produce a hybrid organic-inorganic and a fully organic spin valve in the form of a supported nanowire of ~200 nm width and several microns length, with a concentric spin valve stack. Three main fabrication techniques will be used: organic Physical Vapor Deposition (O-PVD), plasma-enhanced Chemical Vapour Deposition (PE-CVD) and remote plasma assisted vacuum deposition (RPAVD). Magnetoresistance measurements will be performed on single nanowires by conducting-probe atomic force microscopy (CP-AFM), and will give the definite measurement of quality of the samples produced
This project will be developed within the Nanotechnology on Surfaces research group (NanoOnSurf), at the Institute of Materials Science of Seville (CSIC – University of Seville), located in the multidisciplinary CicCartuja research centre (Seville, Spain). State-of-the-art synthesis and characterisation techniques developed in the host research group will be the key for the success of this proposal.
This project is directly related with Horizon 2020 Work Programme 2014-2015, chapter 5.i, action ICT 3 – 2014: Advanced Thin, Organic and Large Area Electronics (TOLAE) technologies, and thus is expected to have a strong impact in the future European electronic industry.
