Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function at very low temperatures, their practical application has been severely ...

Researchers have achieved a major breakthrough by generating quantum spin currents in graphene—without relying on bulky magnetic fields. By pairing graphene with a magnetic material, they unlocked a ...

An international research team have observed “orbital pumping,” a new phenomenon in which orbital currents are generated from the precession of magnetization in magnetic materials. Microwave-induced ...

Scientists from TU Delft (The Netherlands) have observed quantum spin currents in graphene for the first time without using magnetic fields. These currents are vital for spintronics, a faster and more ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...
