Effect of C-face 4H-SiC(0001) deposition on thermopower of single and multilayer graphene in AA, AB and ABC stacking

Giovanni Pizzi

The Seebeck coefficient in multilayer graphene is investigated within the density-functional theory, using the semiclassical Boltzmann equations and interpolating the bands in a maximally-localized Wannier functions basis set. We compare various graphene s ...

Functionalized graphene grown by oxidative dehydrogenation chemistry

László Forró, Arnaud Magrez, Endre Horvath, Arnaud Walter, Daniel Oberli, Massimo Spina, Jacim Jacimovic, Laurent Syavoch Bernard

We report on a highly efficient growth of graphene using dehydrogenation of acetylene by an oxidative reaction with carbon dioxide. In few seconds, large-area of copper foil used as catalyst of the reaction is fully covered with graphene. The yield of the ...

Periodic and Quasi-Periodic Graphene-Based Reconfigurable Surfaces

Julien Perruisseau-Carrier

We present recent results related to the modelling, design, and application of graphene surfaces. Mono and multilayer graphene surfaces are patterned in a periodic or quasi-periodic manner to tailor their electromagnetic response in terms of magnitude, pha ...

The shear mode of multilayer graphene

Nicola Marzari, Yi Wang, Hui Wang

The quest for materials capable of realizing the next generation of electronic and photonic devices continues to fuel research on the electronic, optical and vibrational properties of graphene. Few-layer graphene (FLG) flakes with less than ten layers each ...

Investigation of the Electromechanical Properties of Graphene

Mohamed Malik Benameur

This thesis studies the optical and electro-mechanical properties of novel atomically thin crystals. It deals with the carbon based material, graphene, and with layered transition metal dichalcogenides with the common formula MX2. The first part describes ...

Reconfigurable terahertz plasmonic antenna concept using a graphene stack

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

The concept and analysis of a terahertz (THz) frequency-reconfigurable antenna using graphene are presented. The antenna exploits dipole-like plasmonic resonances that can be frequency-tuned on large range via the electric field effect in a graphene stack. ...

Determination of minimum conductivity of graphene from contactless microwaves measurements

Mihai Adrian Ionescu, Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz, Pankaj Sharma

We report a non-direct method to determine the minimum conductivity (sigma(min)) of graphene. The proposed technique is based on the prior characterization of graphene sheet impedance at microwave frequencies using waveguides, and on the subsequent extract ...

Defects and localization in chemically-derived graphene

László Forró, Arnaud Magrez, Andrzej Sienkiewicz, Richard Gaal, Luka Ciric, Jacim Jacimovic, George Cristian Vaju

We have performed electron spin resonance (ESR) measurements on a large assembly of graphene oxide (GO) and reduced graphene oxide (RGO) flakes. In GO samples the Curie tail is coming from 1.4 x 10(18) cm(-3) of localized spins. Although reduction of GO wa ...

Graphene-based Field-effect Transistors

Adarsh Singh Sagar

With transistors set to reach their smallest possible size in the next decade, the silicon chip is likely to change dramatically, or be replaced entirely. The transistor industry's path which has been largely shaped by Gordon Moore's famous prediction that ...
