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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Imagine a super-cold, ultra-thin layer of electrons trapped in a strong magnetic field. Normally, electrons move independently, ...

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 ...

If one side of a conducting or semiconducting material is heated while the other remains cool, charge carriers move from the hot side to the cold side, generating an electrical voltage known as ...

Researchers demonstrate orbital hybridization in graphene-based quantum dots, revealing how anisotropic confinement influences electronic states at the atomic scale. Quantum dots, often described as ...
