Researcher at Brown University have discovered a new, curvature-localizing, subcritical buckling mode that produces shallow-kink corrugation in multi-layer graphene. Density functional theory analysis reveals the curvature that connects two regions of uniformly but oppositely sheared stacks of flat atomic sheets. The high polarization concentration, predicted by the model, can be controlled by macroscopic deformation and is expected to be useful in studies of selective graphene-surface functionalization for various applications… read more.
