Graphene on the way to superconductivity

Posted: 09 Nov 2018 12:01 PM PST

Scientists have found evidence that double layers of graphene have a property that may let them conduct current completely without resistance. They probed the band structure at BESSY II with extremely high resolution ARPES and could identify a flat area at a surprising location.

Technique for preventing extraction of finger vein patterns from photographs
