n -dependent interlayer exchange energy ratio J / J 0 (cyan diamonds for experimental data, orange diamonds for DFT calculations). J 0 is the interlayer exchange energy at the lowest doping, {J}_{0}^{{\rm{DFT}}} ( n = 0) = 1.1 meV for the DFT calculations, and {J}_{0}^{{\rm{EXP}}} ( n = 1.75 10 11 cm -2 ) = 0.58 meV for the experimental values (a trend towards flattening seen in the DFT calculations at large n remains to be understood).
