Enhanced Superconductivity of Hydrogenated β Borophene.

Borophene stands out among elemental two-dimensional materials due to its extraordinary physical properties, including structural polymorphism, strong anisotropy, metallicity, and the potential for phonon-mediated superconductivity. However, confirming superconductivity in borophene experimentally has been evasive to date, mainly due to the detrimental effects of metallic substrates and its susceptibility to oxidation. In this study, we present an analysis of superconductivity in the experimentally synthesized hydrogenated β borophene, which has been proven to be less prone to oxidation.
