Graphene exhibits unique electronic properties, and its low dimensionality, structural robustness, and high work-function make it very promising as the charge storage media for memory applications. Along with the development of miniaturized and scaled up devices, nanostructured graphene emerges as an ideal material candidate. Here we proposed a novel non-volatile charge trapping memory utilizin...

Self-assembly of biological molecules on solid materials is central to the "bottom-up" approach to directly integrate biology with electronics. Inspired by biology, exquisite biomolecular nanoarchitectures have been formed on solid surfaces. We demonstrate that a combinatorially-selected dodecapeptide and its variants self-assemble into peptide nanowires on two-dimensional nanosheets, single-la...

Here, we report a facile method to fabricate a graphene nanomesh (GNM) by using a platinum (Pt) metal nano-network as a pattern mask. A hexagonally ordered Pt nano-network (i.e. nanomesh) with high-density arrays of periodic nano-holes was synthesized using an anodized alumina template, which served perfectly as a pattern mask for generating GNMs with tunable pore neck widths. Altering the neck...

The existence of an energy gap of graphene is vital as far as nano-electronic applications such as nano-transistors are concerned. In this paper, we present a method for introducing arbitrary energy gaps through breaking the symmetry point group of graphene. We investigate the tight-binding approximation for the dispersion of π and π∗ electronic bands in patterned graphene including up to five ...

First-principles calculations demonstrate that line/ribbon defects, resulting from a controlled dehydrogenation in graphane, lead to the formation of low-dimensional electron-rich tracks in a monolayer. The present simulations point out that hybrid graphane-graphene nanostructures exhibit important elements, greatly required for the fabrication of efficient electronic circuits at the atomic level.

Two-dimensional materials are popular in design of nanodevices. To improve bending stiffness few-layered graphene ribbon, the relative sliding between neighboring layers should be avoided by method such as bonding them together. In this study, new bonds ribbon formed ballistic C60 fullerenes from both surfaces ribbon. Collision effects evaluated through molecular dynamics simulations. The forma...

The combined effects of an asymmetric (square or V-shaped) notch and uniaxial strain are studied in a zigzag graphene nanoribbon (ZGNR) device using a generalized tight-binding model. The spin-polarization and conductance-gap properties, calculated within the Landauer–Büttiker formalism, were found to be tunable for uniaxial strain along the ribbon-length and ribbon-width for an ideal ZGNR and ...

We use the averaging method in order to obtain the values of the energy levels of a graphene ribbon under a magnetic field with some given conditions. We contrast the efficiency of the method with other methods for two different choices of the magnetic field. 2014 Elsevier Inc. All rights reserved.

Graphene, a recently discovered form of carbon, has received much attention over the past few years due to its excellent electrical, optical, and thermal properties [1]. With an extraordinary carrier mobility and high current density [2], graphene's application in electronic devices is promising. As a zero bandgap material, pristine graphene cannot be used as a semi-conducting channel in transi...
