Ripples in isotropically compressed graphene

Band narrowing and Mott localization in isotropically superstrained graphene

Characteristics of Graphene-Filled Solderable Isotropically Conductive Adhesive (ICA)

A new class of functionalized graphene-filled solderable isotropically conductive adhesive (ICA) has been developed using a low-meltingpoint alloy (LMPA) fillers. The mechanical and electrical characteristics of formulated ICAs were investigated and compared with those of three kinds of conventional ICAs filled with Ag particles. The functionalized graphene-filled solderable ICA formed good met...

Direct imaging of atomic-scale ripples in few-layer graphene.

Graphene has been touted as the prototypical two-dimensional solid of extraordinary stability and strength. However, its very existence relies on out-of-plane ripples as predicted by theory and confirmed by experiments. Evidence of the intrinsic ripples has been reported in the form of broadened diffraction spots in reciprocal space, in which all spatial information is lost. Here we show direct...

Effect of Intrinsic Ripples on Elasticity of the Graphene Monolayer

The effect of intrinsic ripples on the mechanical response of the graphene monolayer is investigated under uniaxial loading using molecular dynamics (MD) simulations with a focus on nonlinear behavior at a small strain. The calculated stress-strain response shows a nonlinear relation through the entire range without constant slopes as a result of the competition between ripple softening and bon...

Increased permeability of oxygen atoms through graphene with ripples.

Graphene is an ideal membrane for selective separation because of its unique properties and single-layer structure. Considerable efforts have been made to alter the permeability of graphene. In this study, we investigate the pathways for an oxygen atom to pass through graphene sheets. We also identify the effect of the ripple's curvature in graphene sheets on the energy barrier of permeation th...
