Recent experimental investigations show that large-area samples of graphene tend to be polycrystalline. Physical properties of such samples are strongly affected by the presence of intrinsic topological defects of polycrystalline materials-dislocations and grain boundaries. This article reviews recent progress in understanding dislocations and grain boundaries in graphene.
Polycrystalline graphene: atomic structure and …
There is growing evidence of the polycrystalline nature of graphene samples at micrometer length scales. Grain boundaries and dislocations, intrinsic topological defects of polycrystalline materials, inevitably affect all kinds of physical properties of graphene.

Polycrystalline graphene and other two-dimensional …
Large-area graphene films, which are necessary for industrial applications, are typically polycrystalline - that is, composed of single-crystalline grains of varying orientation joined by grain boundaries. Here, we present a review of the large body of research reported in the past few years on polycrystalline graphene.
Scaling Properties of Charge Transport in …
2013-4-10 · Polycrystalline graphene is a patchwork of coalescing graphene grains of varying lattice orientations and size, resulting from the chemical vapor deposition (CVD) growth at random nucleation sites on metallic substrates. The morphology of grain boundaries has become an important topic given its fundamental role in limiting the mobility of ...
Scale-invariant large nonlocality in polycrystalline …
Considering the microscopic details of the fabricated samples and the polycrystalline morphology of the CVD graphene samples, the large nonlocal signals are consistent with a dissipative quantum ...
On the crumpling of polycrystalline graphene by …
Crumpled graphene has been emerging as a valuable component for a variety of devices such as supercapacitors or hydrophobic surface coatings due to its geometric change from a 2D to a 3D structure accompanied by changes in its material behavior. As polycrystalline graphene …
