Graphene Nano-Ribbon Electronics
We have fabricated graphene nano-ribbon field-effect transistor devices and investigated their electrical properties as a function of ribbon width. Our experiments show that the resistivity of a ribbon increases as its width decreases, indicating the impact of edge states. Analysis of temperature dependent measurements suggests a finite quantum confinement gap opening in narrow ribbons. The ele...
متن کاملGraphene nano-floating gate transistor memory on plastic.
A transparent flexible graphene nano-floating gate transistor memory (NFGTM) device was developed by combining a single-layer graphene active channel with gold nanoparticle (AuNP) charge trap elements. We systematically controlled the sizes of the AuNPs, the thickness of the tunneling dielectric layer, and the graphene doping level. In particular, we propose that the conductance difference (i.e...
متن کاملBuckled circular monolayer graphene: a graphene nano-bowl.
We investigate the stability of circular monolayer graphene subjected to a radial load using non-equilibrium molecular dynamics simulations. When monolayer graphene is radially stressed, after some small circular strain (∼0.4%) it buckles and bends into a new bowl-like shape. Young's modulus is calculated from the linear relation between stress and strain before the buckling threshold, which is...
متن کاملTunable graphene-based plasmonic waveguides: nano modulators and nano attenuators
O R IG IN A L P A P ER Abstract A modulation principle and method, the gatevoltage-controlled mode-guiding switching/mode-cutoff mechanism, is proposed and numerically investigated to achieve the modulation/attenuation function. The propagating attenuation of the graphene 2D waveguide as a function of the Fermi level of the cladding is analyzed. Different modes with low or high attenuations in ...
متن کاملNano-scale strain engineering of graphene and graphene-based devices
Structural distortions in nano-materials can induce dramatic changes in their electronic properties. This situation is well manifested in graphene, a two-dimensional honeycomb structure of carbon atoms with only one atomic layer thickness. In particular, strained graphene can result in both charging effects and pseudo-magnetic fields, so that controlled strain on a perfect graphene lattice can ...
