Researchers take a step towards achieving topological qubits in graphene

Researchers from Spain, Finland and France have demonstrated that magnetism and superconductivity can coexist in graphene, opening a path towards graphene-based topological qubits.Schematic illustration of the interplay of magnetism and superconductivity in a graphene...

Researchers produce extremely conductive graphene-enhanced hydrogel for medical applications

An interdisciplinary research team of the Research Training Group (RTG) 2154 “Materials for Brain” at Kiel University (CAU) has developed a method to produce graphene-enhanced hydrogels with an excellent level of electrical conductivity. What makes this...

Researchers find surprising electron interaction in ‘magic-angle’ graphene

A research team, led by Brown University physicists, has found a new way to precisely probe the nature of the superconducting state in magic-angle graphene. The technique enables researchers to manipulate the repulsive force – the Coulomb interaction – in...
Researchers create tunable superconductivity in magic-angle twisted trilayer graphene

Researchers create tunable superconductivity in magic-angle twisted trilayer graphene

When two sheets of graphene are stacked atop each other at just the right angle, the layered structure morphs into an unconventional superconductor, allowing electric currents to pass through without resistance or wasted energy. This “magic-angle” transformation in...
