Enhanced Manifold of States Achieved in Heterostructures of Iron Selenide and Boron-Doped Graphene
نویسندگان
چکیده
Enhanced superconductivity is sought by employing heterostructures composed of boron-doped graphene and iron selenide. Build-up of a composite manifold of near-degenerate noninteracting states formed by coupling top-of-valence-band states of FeSe to bottom-of-conductionband states of boron-doped graphene is demonstrated. Intraand intersubsystem excitons are explored by means of density functional theory in order to articulate a normal state from which superconductivity may emerge. The results are discussed in the context of electron correlation in general and multi-band superconductivity in particular.
