  The element boron has long been central to two-dimensional superconducting
materials, and numerous studies have demonstrated the presence of
superconductivity in various boron-based structures. Recent work introduced a
new variant: Bilayer Kagome borophene, characterized by its bilayer Kagome
lattice with van Hove singularity. Using first-principles calculations, our
research investigates the unique electronic structure and superconducting
properties of Bilayer Kagome borophene (BK-borophene) through first-principles
calculations. BK-borophene is identified as a single-gap superconductor with an
initial superconducting transition temperature (Tc) of 11.0 K. By strategically
doping the material to align its Fermi level with the Van Hove singularity, Tc
is significantly enhanced to 30.0 K. The results contribute to the existing
understanding of BK-borophene, highlighting its potential as a member of the
expanding family of two-dimensional superconducting materials.
