What Happens Between the Sheets? Extremely-Promising Superconductor Surprises Everyone ‘Floating’ Graphene on a Bed of Calcium AtomsAdding calcium to graphene creates an extremely-promising superconductor, but where does the calcium go?Adding calcium to a composite graphene-substrate structure creates a high transition-temperature (Tc) superconductor.In a new study, an Australian-led team has for the first time confirmed what actually happens to those calcium atoms: surprising everyone, the calcium goes underneath both the upper graphene sheet and a lower ‘buffer’ sheet, ‘floating’ the graphene on a bed of calcium atoms.Superconducting calcium-injected graphene holds great promise for energy-efficient electronics and transparent electronics.Read more. -- source link
