Anisotropic hydrogen etching of chemical vapor deposited graphene.
We report a simple, clean, and highly anisotropic hydrogen etching method for chemical vapor deposited (CVD) graphene catalyzed by the copper substrate. By exposing CVD graphene on copper foil to hydrogen flow around 800 °C, we observed that the initially continuous graphene can be etched to have many hexagonal openings. In addition, we found that the etching is temperature dependent. Compared ...
متن کاملTunneling characteristics in chemical vapor deposited graphene – hexagonal boron nitride – graphene junctions
Large area chemical vapor deposited graphene and hexagonal boron nitride was used to fabricate graphene – hexagonal boron nitride – graphene symmetric field effect transistors. Gate control of the tunneling characteristics is observed similar to previously reported results for exfoliated graphene – hexagonal boron nitride – graphene devices. Density-of-states features are observed in the tunnel...
متن کاملReview of chemical vapor deposition of graphene and related applications.
Since its debut in 2004, graphene has attracted enormous interest because of its unique properties. Chemical vapor deposition (CVD) has emerged as an important method for the preparation and production of graphene for various applications since the method was first reported in 2008/2009. In this Account, we review graphene CVD on various metal substrates with an emphasis on Ni and Cu. In additi...
متن کاملControllable Synthesis of Graphene by Plasma‐Enhanced Chemical Vapor Deposition and Its Related Applications
Graphene and its derivatives hold a great promise for widespread applications such as field-effect transistors, photovoltaic devices, supercapacitors, and sensors due to excellent properties as well as its atomically thin, transparent, and flexible structure. In order to realize the practical applications, graphene needs to be synthesized in a low-cost, scalable, and controllable manner. Plasma...
متن کاملLateral Fusion of Chemical Vapor Deposited N = 5 Armchair Graphene Nanoribbons
Bottom-up synthesis of low-bandgap graphene nanoribbons with various widths is of great importance for their applications in electronic and optoelectronic devices. Here we demonstrate a synthesis of N = 5 armchair graphene nanoribbons (5-AGNRs) and their lateral fusion into wider AGNRs, by a chemical vapor deposition method. The efficient formation of 10- and 15-AGNRs is revealed by a combinati...
