A team of researchers at Korean state-invested Institute for Basic Science (IBS) has successfully cultivated world’s first graphene without wrinkles, folds, and ad-layers, raising the prospect of becoming a next-generation semiconductor material. The Ministry of Science and ICT said Thursday that the team – led by Director Rod Ruoff at the Center for Multidimensional Carbon Materials within the institute – has achieved new discovery of fold-free and ad-layer free single-crystal graphene. Graphene, which consists of carbon atoms, is thin and transparent but is 200 times stronger than steel while flowing 100 times in faster current than copper. It is referred to as “dream novel material” in the semiconductor sector but was yet to be perfected without wrinkles and folds. The research has been published their breakthrough in the journal Nature.
