Graphene Based Mechanical Resonators Fabricated via Direct Dry Transfer

Luis Guillermo Villanueva Torrijo, Tom Larsen, Marco Di Gisi

We present here the fabrication of large suspended sheets of graphene for mechanical resonators. The diameter of the circular resonators varies from 1.2 μm to 26.5 μm resulting in diameter-to-thickness aspect ratios as large as 74000. The membranes were fa ...

Current-Induced Spin Polarization in Topological Insulator-Graphene Heterostructures

Klaus Kern, Marko Burghard, Alexander Ronald Hoyer, Kristina Vaklinova

Further development of the field of all-electric spintronics requires the successful integration of spin transport channels with spin injector/generator elements. While with the advent of graphene and related 2D materials high performance spin channel mate ...

Transport, magnetic and vibrational properties of chemically exfoliated few-layer graphene

László Forró, Bálint Náfrádi, Péter Szirmai, Ferenc Simon, Bence Gábor Márkus

We study the vibrational, magnetic and transport properties of Few Layer Graphene (FLG) using Raman and electron spin resonance spectroscopy and microwave conductivity measurements. FLG samples were produced using wet chemical exfoliation with different po ...

Strong Interplay between the Electron Spin Lifetime in Chemically Synthesized Graphene Multilayers and Surface-Bound Oxygen

László Forró, Bálint Náfrádi

The electron spin lifetime in an assembly of chemically synthesized graphene sheets was found to be extremely sensitive to oxygen. Introducing small concentrations of physisorbed O-2 onto the graphene surface reduced the exceptionally long 140 ns electron ...

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 ...

Strong interface-induced spin-orbit interaction in graphene on WS2

Helmuth Berger, Zhe Wang, Hua Chen

Interfacial interactions allow the electronic properties of graphene to be modified, as recently demonstrated by the appearance of satellite Dirac cones in graphene on hexagonal boron nitride substrates. Ongoing research strives to explore interfacial inte ...

Doping characteristics of iodine on as-grown chemical vapor deposited graphene on Pt

Olivier Renault, Hokwon Kim, Nicolas Chevalier

Using laboratory X-ray photoelectron emission microscopy (XPEEM), we investigated the doping efficiency and thermal stability of iodine on as-grown graphene on Pt. After iodine adsorption of graphene in saturated vapor of I-2, monolayer and bilayer graphen ...

Tunable Carrier Multiplication and Cooling in Graphene

Marco Grioni, Alberto Crepaldi, Jens Christian Johannsen

Time- and angle-resolved photoemission measurements on two doped graphene samples displaying different doping levels reveal remarkable differences in the ultrafast dynamics of the hot carriers in the Dirac cone. In the more strongly (n-)doped graphene, we ...
