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
