Electronic transport in B-N substituted bilayer graphene nanojunctions

Daniele Giofré

We investigated a suspended bilayer graphene where the bottom/top layer is doped by boron/nitrogen substitutional atoms. By using density functional theory calculations, we found that at high dopant concentration (one B-N pair every 32 C atoms), the electr ...

2D Material-Based Bolometer

Tom Larsen, Marco Di Gisi

Measurement of thermal radiation through uncooled bolometers is at the heart of many industrial applications. From the development of the Honey- well silicon microstructure developed in 1982, no particular change in paradigm was recorded. The advent of 2D- ...

Extreme laser spectral broadening driven by intense THz field

Christoph Peter Hauri, Mostafa Shalaby

We present giant spectral broadening by cross phase modulation of a 60 fs nIR pulse in GaP by means of an intense Terahertz transient. The THz field induces up to 500% spectral broadening supporting sub-10 fs nIR pulses. ...

During the past decade, graphene --- a monolayer of carbon atoms --- has attracted enormous interest for its use in nanoelectronic device applications. The absence of bandgap, however, has stalled its use both in logic (inability to turn off) and radio fre ...

Graphene

Laurent Syavoch Bernard

We report a full study of graphene synthesis by CVD on Cu surface. Two CVD methods have been developed. The first is a static one, which yields monolayer of graphene at low pressure of methane in 3 minutes at 1000 C. The second one is an equimolar method w ...

Self-biased reconfigurable graphene stacks for terahertz plasmonics

Mihai Adrian Ionescu, Arnaud Magrez, Clara-Fausta Moldovan, Julien Perruisseau-Carrier, Santiago Capdevila Cascante, Laurent Syavoch Bernard

The gate-controllable complex conductivity of graphene offers unprecedented opportunities for reconfigurable plasmonics at terahertz and mid-infrared frequencies. However, the requirement of a gating electrode close to graphene and the single 'control knob ...

Sub-Terahertz Frequency-Domain Spectroscopy Reveals Single-Grain Mobility and Scatter Influence of Large-Area Graphene

Klaus Kern, Marko Burghard, Alexander Ronald Hoyer

The response of individual domains in wafer-sized chemical vapor deposition graphene is measured by contactless sub-terahertz interferometry, observing the intrinsic optical conductance and reaching very high mobility values. It is shown that charged scatt ...

Ultrafast electron dynamics in epitaxial graphene investigated with time- and angle-resolved photoemission spectroscopy

Marco Grioni, Alberto Crepaldi, Jens Christian Johannsen

In order to exploit the intriguing optical properties of graphene it is essential to gain a better understanding of the light-matter interaction in the material on ultrashort timescales. Exciting the Dirac fermions with intense ultrafast laser pulses trigg ...

Gate-controlled mid-infrared light bending with aperiodic graphene nanoribbons array

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

Graphene plasmonic nanostructures enable subwavelength confinement of electromagnetic energy from the mid-infrared down to the terahertz frequencies. By exploiting the spectrally varying light scattering phase at the vicinity of the resonant frequency of t ...
