Since the first isolation of graphene in 2004 [1], the scientific community has moved towards new 2D materials with (more) interesting properties. As a matter of fact, despite its numerous qualities that have made it a champion of 2D materials, graphene is still a semi-metal, and until now, no stable 2D material with metallic behavior had been identified. Recently however, it was theoretically demonstrated that a mono-atomic 2D layer of boron, borophene, would present such a metallic behavior with a relatively high electron mobility [2,3]. Moreover, borophene would possess a 100% optical transmittance in the visible range – which would make borophene more transparent than graphene [3]. Interestingly, the chemical boron–boron bond is almost as strong as the carbon-carbon one, and borophene would thus possess mechanical properties close to the ones of graphene [4]. Borophene should also be super-stretchable and super-flexible, it should present stress-induced allotropic transitions [5–7] and even a superconducting behavior [8,9]. Combining all these properties (Figure 1), borophene could be an excellent candidate for use as an anode [10,11] or electrical contact [12]...... |
