Artificial Graphene — Material Similar To Graphene Created From Nanometer-Thick Semiconductor Crystals

A potentially revolutionary new material, described as a sort of “artificial graphene,” has been created by researchers at the University of Luxembourg. The material — which is essentially the same thing as graphene, except that instead of carbon molecules, nanometer-thick semiconductor crystals are used — should lead to improvements to … [continued]
