High-Frequency Noise Characterization and Modeling of Graphene Field-Effect Transistors

Marina Deng, Dalal Fadil, Wei Wei, Emiliano Pallecchi, Henri Happy, Gilles Dambrine, Magali de Matos, Thomas Zimmer, Sébastien Frégonèse

This article presents the small-signal and noise characterization of different technologies based on chemical vapor deposition (CVD) and silicon-carbide (SiC) graphene field-effect transistors (GFETs). The noise model, built on noise figure measurements under 50 Ω using the F 50 method, was…

Demonstrating full integration process for electroactive polymer microtransducers to realize soft microchips

Lauréline Seurre, Kätlin Rohtlaid, Giao T. M. Nguyen, Caroline Soyer, Sofiane Ghenna, Sébastien Grondel, Frederic Vidal, Barthelemy Cagneau, Cedric Plesse, Eric Cattan

Actuation and sensing with electroactive polymers should be a chance for flexible MEMS but their micromachining and integration are still not mature. Some innovative materials and microfabrication processes are still expected. In this paper, a first full elaboration of polymeric microtransducers (…

A superheterodyne 300 GHz wireless link for ultra-fast terahertz communication systems

Iulia Dan, Guillaume Ducournau, Shintaro Hisatake, Pascal Szriftgiser, Ralf-Peter Braun, Ingmar Kallfass

A superheterodyne transmission scheme is adopted and analyzed in a 300 GHz wireless point-to-point link. This was realized using two different intermediate frequency (IF) systems. The first uses fast digital synthesis which provides an IF signal centered around a carrier frequency of 10 GHz. The…

Long-range electron transport in Prussian blue analog nanocrystals

Roméo Bonnet, Stéphane Lenfant, Sandra Mazérat, Talal Mallah, Dominique Vuillaume

We report electron transport measurements through nano-scale devices consisting of 1 to 3 Prussian blue analog (PBA) nanoparticles connected between two electrodes. We compare two types of cubic nanoparticles, CsCo^IIIFe^II (15 nm) and CsNi<sup>II…

Experimental observation and modeling of the impact of traps on static and analog/HF performance of graphene transistors

Anibal Pacheco-Sanchez, Nikolaos Mavredakis, Pedro C. Feijoo, Wei Wei, Emiliano Pallecchi, Henri Happy, David Jimenez

The trap-induced hysteresis on the performance of a graphene field-effect transistor is experimentally diminished here by applying consecutive gate-to-source voltage pulses of opposing polarity. This measurement scheme is a practical and suitable approach to obtain reproducible device…

Terahertz spintronic emitter with arbitrarily controllable linear polarization properties not needing a rotating magnetic bias

Pierre Kolejak, Kamil Postava, Jean-Francois Lampin, Nicolas Tiercelin, Mathias Vanwolleghem

Spintronic THz emitters are new intensively studied sources of THz radiation with high potential in broadband THz time-domain spectroscopy. We present a novel architecture for a spintronic emitter based on a ferromagnetic heterostructure with an induced in-plane magnetic anisotropy. This new…
