Popis:	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.
