 New study reveals unexpected softness of bilayer graphene30 April 2020In the study, published in the journal Physical Review B, the researchers showed that bilayer graphene, consisting of two layers of graphene, was noticeably softer than both two-dimensional (2D) graphene and three-dimensional (3D) graphite along the stacking direction. This surprising result differs from previous research which showed that 2D graphene, … [more] | ||
