Synthesizing a unique nanographene may advance spintronics applications

Graphene, despite its excellent mechanical, electronic and optical properties, is traditionally not deemed suitable for magnetic applications. Swiss Federal Laboratories for Materials Science and Technology (EMPA) Researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic properties that could permit future spintronics applications.

Depending on the shape and orientation of their edges, graphene nanostructures (also known as nanographenes) can have very different properties. Together with colleagues from the Technical University in Dresden, Aalto University in Finland, Max Planck Institute for Polymer Research in Mainz and University of Bern, Empa researchers have succeeded in building a nanographene with magnetic properties that could be a decisive component for spin-based electronics functioning at room temperature.

Groningen team creates graphene-based 2D spin transistor

Physicists from the University of Groningen constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) was placed on top of the graphene to induce charge-to-spin conversion in the graphene.

Spintronics is an attractive alternative way of creating low-power electronic devices. It is not based on a charge current but rather on a current of electron spins. Spin is a quantum mechanical property of an electron, a magnetic moment that could be used to transfer or store information.

The Graphene Flagship is looking for new industrial partners for its core 3 project

The Graphene Flagship has announced a call out for new industrial partners to bring specific industrial and technology transfer competences or capabilities that complement the present GF consortium in the next core project (Core 3).

The Graphene Flagship is looking for companies with specific expertise - for example MRAM tools developers to leverage solutions for graphene-spintronic stacks, developers of graphene related materials based laser systems and instrumentations for coherent Raman imaging, makers of graphene-based fibers, yarns and textiles, automotive companies with expertise in fuel-cells, industrial graphene-based supercapacitors makers and more.

The Graphene Flagship announces its 2019-2030 graphene application roadmap

The EU Graphene Flagship has published its graphene application roadmap, showing when the flagship expects different graphene applications to mature and enter the market.

Graphene Flagship roadmap 2019-2030 photoAs can be seen in the roadmap above (click here for a larger image), the first applications that are being commercialized now are applications such as composite functional coatings, graphene batteries, low-cost printable electronics (based on graphene inks), photodetectors and biosensors.
