Crystal structure evolution of individual graphene islands during CVD growth on copper foil.
نویسندگان
چکیده
Single-crystal percentage of graphene islands on Cu foil is associated with island sizes and shapes. In polycrystalline islands, certain grain boundary types are favored. There is no obvious relation between the number of lobes and grain orientations. An observed structure evolution and surface disorder of Cu grains can be possible factors for the formation of grain boundaries within graphene islands.

Graphene Crystal Growth Engineering on Epitaxial Copper Thin Films
In this work 1 , we study graphene growth dynamics on epitaxial Cu thin film substrates by chemical vapor deposition (CVD). These surfaces have a single crystallographic orientation and are atomically smooth, unlike their foil counterparts, making them better platforms on which to reproducibly synthesize highquality graphene and study crystal growth evolution. Consequently, we gained novel insi...

متن کاملRegulating Top-surface Graphene Growth by “Gettering” Carbon Diffusion at Backside of the Copper Foil
We reported a simple and practical strategy that enables us to control the nucleation density and growth kinetics for graphene grown on the top-surface of metal substrate through gettering the carbon source on the backside of the flat Cu foil, during chemical vapor deposition (CVD). Hitherto, for CVD graphene grown on a flat Cu foil, merely topsurface-based growth mechanism has been emphasized,...
متن کاملFrictional behavior of atomically thin sheets: hexagonal-shaped graphene islands grown on copper by chemical vapor deposition.
Single asperity friction experiments using atomic force microscopy (AFM) have been conducted on chemical vapor deposited (CVD) graphene grown on polycrystalline copper foils. Graphene substantially lowers the friction force experienced by the sliding asperity of a silicon AFM tip compared to the surrounding oxidized copper surface by a factor ranging from 1.5 to 7 over loads from the adhesive m...

The electrical performance of graphene synthesized by chemical vapor deposition and transferred to insulating surfaces may be compromised by extended defects, including for instance grain boundaries, cracks, wrinkles, and tears. In this study, we experimentally investigate and compare the nano- and microscale electrical continuity of single layer graphene grown on centimeter-sized single crysta...
