Graphene Staying Strong Although exfoliated graphene can be extremely strong, it is produced on too small a scale for materials application. Graphene can be produced on a more practical scale by chemical vapor deposition, but the presence of grain boundaries between crystallites apparently weakens the material. Lee et al. (p. 1073) show that postprocessing steps during the removal of the graphene sheets can oxidize the grain boundaries and weaken them. If these steps are avoided, the material… 

Charge Transport in Polycrystalline Graphene: Challenges and Opportunities

Numerical simulations and transport measurements are used to demonstrate that electrical properties and chemical modification of graphene grain boundaries are strongly correlated, which provides guidelines for the improvement of graphene devices and opens a new research area of engineering graphenegrain boundaries for highly sensitive electro-biochemical devices.

Enhancing the Strength of Graphene by a Denser Grain Boundary.

A systematic study on the effect of elastic modulus and breaking strength of CVD-derived graphene films with a controlled density and distribution ofGBs finds that graphene films become much stronger by hugely increasing the density of GBs without triple junctions formed inside, in analogy to the two-dimensional plum pudding structures.

Mechanisms and criteria for failure in polycrystalline graphene

No Tilt Angle Dependence of Grain Boundary on Mechanical Strength of Chemically Deposited Graphene Film

Although graphene has been successfully grown in large scale via chemical vapor deposition (CVD), it is still questionable whether the mechanical properties of CVD graphene are equivalent to those of

Single-crystal, large-area, fold-free monolayer graphene.

The wrinkling/folding process for graphene films grown from an ethylene precursor on single-crystal Cu-Ni(111) foils is explored, and a critical growth temperature is identified above which folds will naturally form during the subsequent cooling process.

Enhancing CVD graphene's inter-grain connectivity by a graphite promoter.

It is demonstrated that the inter-grain connectivity can be significantly improved by adding a second material in the vicinity of the growth substrate to decrease the amount of structural defects that remain at the grain boundaries of conventionally grown graphene even after 6 hour growth.

Chemical Vapour Deposition and Electron Microscopy Analysis of Graphene

Graphene is a promising material for many applications, including electronics, energy technologies, chemical filters and mechanical materials. In this work, graphene has been grown by chemical vapour

Determination of the elastic moduli of CVD graphene by probing graphene/polymer Bragg stacks

Graphene has been widely used in the form of micro-flakes to fabricate composite materials with enhanced mechanical properties. Due to the small size of the inclusions and their random orientation



Control and characterization of individual grains and grain boundaries in graphene grown by chemical vapour deposition.

It is shown that grain boundaries give a significant Raman 'D' peak, impede electrical transport, and induce prominent weak localization indicative of intervalley scattering in graphene, opening a route towards scalable fabrication of single-crystal graphene devices without grain boundaries.

Chemical vapor deposition-derived graphene with electrical performance of exfoliated graphene.

The electrical transport properties of CVD-grown graphene are tested in which two important sources of disorder, namely grain boundaries and processing-induced contamination, are substantially reduced, confirming the possibility of achieving high-performance graphene devices based on a scalable synthesis process.

Tailoring Electrical Transport Across Grain Boundaries in Polycrystalline Graphene

This study suggests that polycrystalline graphene with good stitching may allow for uniformly high electrical performance rivaling that of exfoliated samples, which is suggested using optimized growth conditions and device geometry.

Grains and grain boundaries in single-layer graphene atomic patchwork quilts

The properties of polycrystalline materials are often dominated by the size of their grains and by the atomic structure of their grain boundaries. These effects should be especially pronounced in

Intrinsic strength and failure behaviors of graphene grain boundaries.

The mechanical properties of 20 representative graphene grain boundaries were studied using density functional theory and molecular dynamics to form a useful picture of the grain boundary effect on the mechanical propertiesof polycrystalline graphene.

Revealing the grain structure of graphene grown by chemical vapor deposition

The physical processes occurring in the presence of disorder: point defects, grain boundaries, etc. may have detrimental effects on the electronic properties of graphene. Here we present an approach

Anomalous Strength Characteristics of Tilt Grain Boundaries in Graphene

Using atomistic calculations, graphene sheets with large-angle tilt boundaries that have a high density of defects are as strong as the pristine material and, unexpectedly, are much stronger than those with low-angle boundaries having fewer defects.

Softened elastic response and unzipping in chemical vapor deposition graphene membranes.

Atomic force microscopy is used to image grain boundaries and ripples in graphene membranes obtained by chemical vapor deposition and reveals that out-of-plane ripples effectively soften graphene's in-plane stiffness.

An overview of how different metals interface with suspended graphene is presented, providing a closer look into the metal-graphene interaction by employing high-resolution transmission electron microscopy, especially using high-angle dark field imaging.

Ripping graphene: preferred directions.

This study provides significant insights into breakdown mechanisms of graphene in the presence of defective structures such as cracks and grain boundaries, and investigates the crystallographic orientations of tears.
