Flat electronic band
WebThe doping is controlled by Eu positioning, allowing for the formation of a K-valley localized single spin-polarized low-dispersive parabolic band close to Fermi energy when Eu is on top and a π* flat band with single spin character when Eu is intercalated underneath graphene. In the latter case, Eu also induces a bandgap opening at the Dirac ...
