Role of Thin Layer of Dielectric Between Two Layers of Bilayer Graphene Superconductors

https://doi.org/10.65770/UVWB1716 ABSTRACT It has been found that a thin, high dielectric constant substrate can suppress superconductivity in twisted bilayer graphene . The high dielectric constant of substrate effectively screens and weakens the strong electronic interactions required for Cooper pair formation in , thereby suggesting that the superconductivity in this system is driven by…
