The superconducting T_c of La3Ni2O7 is controlled by the d_x2-y2 orbital filling and the interlayer magnetic exchange J_perp, so clean electron doping should raise T_c.

Hole-doped spin multimer systems exhibit superconductivity signatures when mapped to the hardcore boson model in the strong-binding-energy limit, with pairing persisting in DMRG simulations of the double Kondo lattice.
Superconductivity in La3Ni2O7 arises from interlayer Cooper pairs of 3d_x2-y2 electrons driven by effective J_perp from Hund-assisted AFM exchange transfer, while localized 3d_z2 electrons form rung singlets that produce a pseudogap but no condensate.

Superconductivity in bilayer La$_3$Ni$_2$O$_7$: A review focusing on the strong-coupling Hund's rule assisted pairing mechanism
Superconductivity in La3Ni2O7 arises from interlayer Cooper pairs of 3d_x2-y2 electrons driven by effective J_perp from Hund-assisted AFM exchange transfer, while localized 3d_z2 electrons form rung singlets that produce a pseudogap but no condensate.
