A large-area 15 nm graphene nanoribbon array patterned by a focused ion beam.
Using a focused ion beam, we patterned epitaxial graphene on SiC into an array of graphene nanoribbons as narrow as 15 nm by optimizing the Ga(+) ion beam current, acceleration voltage, dwell time, beam center-to-center distance and ion dose. The ion dose required to completely etch away graphene on SiC was determined and compared with the Monte Carlo simulation result. In addition, a photodete...
متن کاملElastic properties of edges in BN and SiC nanoribbons and of boundaries in C-BN superlattices: A density functional theory study
Using density functional theory calculations, we compute the edge energies and stresses for edges of SiC and BN nanoribbons, and the boundary energies and stresses for domain boundaries of graphene-BN superlattices. SiC and BN armchair nanoribbons show pronounced edge relaxations, which obliterate the threefold oscillatory behavior of the edge stress reported for graphene. Our calculations show...
متن کاملSynthesis of quasi-free-standing bilayer graphene nanoribbons on SiC surfaces
Scaling graphene down to nanoribbons is a promising route for the implementation of this material into devices. Quantum confinement of charge carriers in such nanostructures, combined with the electric field-induced break of symmetry in AB-stacked bilayer graphene, leads to a band gap wider than that obtained solely by this symmetry breaking. Consequently, the possibility of fabricating AB-stac...
متن کاملScalable templated growth of graphene nanoribbons on SiC.
In spite of its excellent electronic properties, the use of graphene in field-effect transistors is not practical at room temperature without modification of its intrinsically semimetallic nature to introduce a bandgap. Quantum confinement effects can create a bandgap in graphene nanoribbons, but existing nanoribbon fabrication methods are slow and often produce disordered edges that compromise...
متن کاملRegular Paper In Situ Study on Oxygen Etching of Surface Buffer Layer on SiC(0001) Terraces
Thermal decomposition of SiC has been used for the fabrication of high quality monolayer graphene and graphene nanoribbons on semi-insulating substrates. In this work, we propose a selective oxygen etching method to remove buffer layers on SiC surfaces that are connected to monolayer graphene formed from step edges. A thermal treatment in an extreme low partial pressure oxygen diluted by argon ...
