Abstract
We use ab initio anisotropic Migdal-Eliashberg formalism to examine the pairing mechanism and the nature of the superconducting gaps in experimentally fabricated borophenes. Our results indicate that the superconducting transition is dominated by a standard phonon-mediated mechanism, and multiple anisotropic superconducting gaps with critical temperatures Tc even approaching 33 K are present in the freestanding form of the fabricated borophenes. These findings provide a different perspective for superconductivity in borophenes.
