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 ab initio analysis of superconductivity in the experimentally synthesized hydrogenated β12 borophene, which has been proven to be less prone to oxidation. Our findings demonstrate that hydrogenation significantly enhances both the stability and superconducting properties of β12 borophene. Furthermore, we reveal that tensile strain and hole doping, achievable through various experimental methods, significantly enhance the critical temperature, reaching up to 29 K. These findings not only promote further fundamental research on superconducting borophene and its heterostructures, but also position hydrogenated borophene as a versatile platform for low-dimensional superconducting electronics.
Researchers are exploring borophene, a two-dimensional material known for its impressive physical properties, including its structure, electrical conductivity, and potential for superconductivity. However, confirming its superconductivity has been difficult due to issues with metallic substrates and oxidation.
Here's a simplified summary:
These findings suggest that hydrogenated borophene could be a promising material for low-dimensional superconducting electronics, paving the way for further research and potential applications.
Monolayer borophene has a high charge capacity, mechanical strength, and low diffusion barrier, but it's not stable enough for practical use
