Nearly a decade ago, researchers heralded the discovery of a new wonder class of ultrathin materials with special optical and electrical properties that made it a potential rival for graphene, a form of carbon discovered in 2004 whose own special properties interest both scientists and engineers.
Now, Caltech engineers have shown that one of these wonder materials, tungsten diselenide, is not just a rival to graphene but also a complement to it. By adding tungsten diselenide to graphene, they have managed to enhance the graphene's electrical properties in ways that enrich our understanding of superconductivity and pave the way for engineering more robust and highly tunable graphene-based superconductors.
