Over a decade ago, researchers at Rice University, including materials scientist Boris Yakobson, theorized that boron atoms would form strong bonds with copper, which would make the synthesis of borophene—a two-dimensional metallic material—difficult. Borophene is composed of a single layer of boron atoms arranged in a sheet, similar to how graphene is structured with carbon atoms. Recent studies have demonstrated that borophene can indeed be synthesized on copper surfaces, overcoming the previously anticipated challenges. This achievement not only confirms the earlier theoretical predictions but also opens up new possibilities for the use of borophene in advanced technologies. Borophene's unique properties, such as high electrical conductivity and mechanical strength, make it a promising candidate for applications in electronics, sensors, and energy storage devices. The ability to reliably produce borophene on copper could facilitate further research and potential commercialization in these fields.
