Superconducting Carbon‐Cage Network with <i>T</i> <sub> <i>c</i> </sub> of 109 K at Ambient Pressure
A novel carbon-cage network was reported, denoted as C<sub>18</sub>, found to be a low energy structure by first principles particle swarm structure search. The compound exhibits high temperature electron-phonon ambient pressure superconductivity with T<sub>c</sub> = 79 K for elemental doping and can be raised to T<sub>c</sub> = 109 K by appropriate hole doping. Analyses of the phonon spectra, molecular dynamics simulations, and enthalpy differences relative to analogous structures synthesized experimentally all suggest that the hole-doped high-T<sub>c</sub> structure is a viable candidate for experimental synthesis.
