…another novel electronic material, graphene. The new class of materials has the potential to be superior to graphene in some aspects, Hasan said, because graphene is a single layer of…
…such as graphene and molybdenum sulfide have created excitement among scientists for their potential to revolutionize transistors and circuits. Research is underway that could vastly increase the efficiency and capabilities…
…tailoring boron-metal interactions. They discovered that copper, a common substrate in graphene growth, might be best to obtain flat boron, while other metals would guide the resulting material in their…
…graphene that has been doped with charge carriers (bottom). For each energy-level transition, an orange line (or purple cloud) appears if that transition is estimated to be faster than one…
…Nature Photonics, Hu and his collaborators have also developed a new way of integrating layers of photonics, made of chalcogenide glass and two-dimensional materials such as graphene, with conventional semiconductor…
…Group/Rice University New research from Rice University shows that nitrogen-doped carbon nanotubes or modified graphene nanoribbons may be suitable replacements for platinum for fast oxygen reduction, the key reaction in…
The branch-and-leaves design is made up of arrays of hollow, cylindrical carbon nanotubes (the “branches”) and sharp-edged petal-like structures (the “leaves”) made of graphene. Tim Fisher/UCLA Engineering Mechanical engineers from…
…graphene oxide, a recently discovered nanomaterial, to manipulate the reaction of fly ash with water and turn the activated fly ash into a strong cement-like material. The graphene oxide rearranges…
…the scientists constructed an ultrathin sandwich of the semiconductor molybdenum ditelluride between layers of carbon graphene. The layered structure was just slightly thicker than the width of a single DNA…
