Researchers Demonstrate Generation and Manipulation of Spin Currents for Advanced Electronic Gadgets

Graphene-based van der Waals heterostructures can be used to create extremely-compact and low-energy electronic gadgets and magnetic memory gadgets, in response to a study led by ICREA Prof. Sergio O. head of the ICN2 Physics and Engineering of Nanodevices Group.

This is what a paper printed in the newest issue of the journal suggests. The outcomes have shown that it’s possible to carry out an efficient and tunable spin-cost conversion in these buildings, and, for the first time, even at room temperature.

The paper is printed in Nature Supplies. The first authors are L. Antonio Benítez and Williams Savero Torres, of the same group. The outcomes complement recent research carried out within this same initiative, along with one printed in 2019 in Nano Letters by scientists from the University of Groningen.

Spintronics, electronics that use electron spin to store, manipulate and transfer data, contains key technologies, comparable to those of motion sensors and information storage applied sciences.

Nonetheless, the development of efficient and versatile spin-based technologies requires high-quality supplies that enable long-distance spin switch, as well as strategies to generate and manipulate spin currents.

Spin currents are usually produced and detected using ferromagnetic supplies. As an alternative, spin-orbit interactions permit the generation and management of spin currents exclusively via electric fields, offering a much more versatile device for the implementation of large-scale spin gadgets.

Graphene is a unique material for long-distance spin transport. The brand new study demonstrates that spin transport may be manipulated in graphene by proximity effects.

To induce these results, the researchers used transition metal dichalcogenides, which are two-dimensional supplies like graphene. The group has demonstrated efficient spin-charge interconversion at room temperature similar to the best performance of conventional materials.
