Graphene FETs Based on High Resolution Nanoribbons for HF Low Power Applications

David Mele, Sarah Mehdhbi, Dalal Fadil, Wei Wei, Abdelkarim Ouerghi, Sylvie Lepilliet, Henri Happy, Emiliano Pallecchi

In this paper we present high frequency field effect transistors based on graphene nanoribbons arrays (GNRFETs). The nanoribbons serve as a channel for the transistors and are fabricated with a process based on e-beam lithography and dry etching of high mobility hydrogen intercalated epitaxial…

Wavefront steering of elastic shear vertical waves in solids via a composite-plate-based metasurface

Jun Zhang, Xiaoshi Su, Yan Pennec, Yun Jing, Xiaofeng Liu, Ning Hu

We report a novel approach to control the wavefronts of shear vertical (SV) waves in solids using metasurfaces constituted by a stacked array of composite plates, which are composed of two connecting parts made of different materials. The metasurfaces are connected at two ends to the halfspace…

Impact of unintentional oxygen doping on organic photodetectors

Julie Euvrard, Amelie Revaux, Alexandra Cantarano, Stephanie Jacob, Antoine Kahn, Dominique Vuillaume

Oxygen plasma is a widely used treatment to change the surface properties of organic layers. This treatment is particularly interesting to enable the deposition from solution of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) on top of the active layer of organic solar cells or…

Continuous-wave infrared optical gain and amplified spontaneous emission at ultralow threshold by colloidal HgTe quantum dots

Pieter Geiregat, Arjan J Houtepen, Laxmi Kishore Sagar, Ivan Infante, Felipe Zapata, Valeriia Grigel, Guy Allan, Christophe Delerue, Dries van Thourhout, Zeger Hens

Abstract Colloidal quantum dots (QDs) raise more and more interest as solution-processable and tunable optical gain materials. However, especially for infrared active QDs, optical gain remains inefficient. Since stimulated emission involves multifold degenerate band-edge states, population…

Optimization of pentacene double floating gate memories based on charge injection regulated by SAM functionalization

S. Li, David Guérin, Stéphane Lenfant, K. Lmimouni

Pentacene based double nano-floating gate memories (NFGM) by using gold nanoparticles (Au NPs) and reduced graphene oxide (rGO) sheets as charge trapping layers are prepared and demonstrated. Particularly, the NFGM chemically treated by 2,3,4,5,6-pentafluorobenzenethiol (PFBT) self-assembled…

Strain-Reduction Induced Rise in Channel Temperature at Ohmic Contacts of GaN HEMTs

Steven Duffy, Brahim Benbakhti, Karol Kalna, Mohammed Boucherta, Wei Zhang, Nour Eddine Bourzgui, Ali Soltani

ABSTRACT Operating temperature distributions in AlGaN/GaN gateless and gated devices are characterized and analyzed using the InfraScope temperature mapping system. For the first time, a substantial rise of channel temperature at the inner ends of ohmic contacts has been observed. Synchrotron…

Design of a thin-plate based tunable high-quality narrow passband filter for elastic transverse waves propagate in metals

J. Zhang, L. H. Zeng, C. L. Hu, W. S. Yan, Yan Pennec, N. Hu

For the elastic SV (transverse) waves in metals, a high-quality narrow passband filter that consists of aligned parallel thin plates with small gaps is designed. In order to obtain a good performance, the thin plates should be constituted by materials with a smaller mass density and Young’s modulus…

Spatiotemporal control of DNA-based chemical reaction network via electrochemical activation in microfluidics

Ievgen Kurylo, Guillaume Gines, Yannick Rondelez, Yannick Coffinier, Alexis Vlandas

In recent years, DNA computing frameworks have been developed to create dynamical systems which can be used for information processing. These emerging synthetic biochemistry tools can be leveraged to gain a better understanding of fundamental biology but can also be implemented in biosensors and…
