Graphene is an atom-thick sheet of carbon with extraordinary electrical characteristics. Many would like to see it used in electronics, but it lacks one important feature, a band gap. Researchers at the University of Luxemberg and other institutions have produced for the first time artificial graphene, which could potentially be engineered with whatever properties are desired.
While some of graphene's properties may come from the carbon it is made of, some do originate from its honeycomb structure. The researchers have recreated that structure but instead of carbon it is made of nanometer-sized, semiconducting crystals. By changing the structure and chemistry of those crystals it will be possible to change the properties of the larger material.
With the ability to tune artificial graphene's properties, this discovery could enable many new systems and technologies in the future that take advantage of the material's extraordinary properties.
