Periodic Reporting for period 1 - ARTEMIS (Graphene Molecule Interfaces for Spintronics)
Reporting period: 2019-09-01 to 2021-08-31
ARTEMIS was developed in response to the increasing demand of new technologies and materials for the transfer and process of information. Within this context, spintronics advances are of paramount importance for conceiving a new generation of fast-computing and low-power consumption devices.
In general, ARTEMIS objectives were:
• The fabrication of spintronics devices operating through graphene/molecule interfaces
• Understanding whether the presence of organic molecules on the surface of graphene can modify the spin transport properties of graphene.
Additionally, ARTEMIS has also focused on the optimization of graphene electrodes to be integrated in the design of organic field-effect transistor (OFET). The fabricated devices demonstrated optimal performance characteristics and constituted a positive contribution to the advance of all-organic based electronics. Such work has resulted in a published research article.
Finally, ARTEMIS resources were also dedicated to further investigation on graphene-based spintronic devices. LSV combining graphene with Van der Waals insulating (Cr2Ge2Te6) and metallic (FeGeTe3) Van der Waals magnets were designed and fabricated. The purpose of such heterostructures consisted in the achievement of injection of a spin current in graphene through all-Van der Waals interface. However, attempts to achieve electrical contacts through the Van der Waals magnets have failed, so that further optimization is needed for advancing in the measurements.
The study of new materials for spintronics is of paramount importance for our society, as the demand for faster and cheaper information technology is rapidly growing. By relying on the transport of the electron spin as an alternative to its charge, spintronic technologies can contribute to reducing power consumption of the electronics available on the market and expand the present market opportunities.
