Extrinsic capacitance extraction for GaAs and GaN FETs from low to high temperatures

Mohammad A. Alim, Ali A. Rezazadeh, Christophe Gaquière, Giovanni Crupi

The main aim of this article is to present an experimental analysis of the thermal influence on the positive derivatives of the real parts of impedance parameters against frequency (PDRZ) for microwave GaN and GaAs based HEMTs. The PDRZ effect is investigated with respect to temperature by both…

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…

Multimodal microscopy test standard for scanning microwave, electron, force and optical microscopy

Olaf C. Haenssler, M. F. Wieghaus, A. Kostopoulos, G. Doundoulakis, E. Aperathitis, S. Fatikow, G. Kiriakidis

We report on measurement results of a test standard suitable for different microscopic modalities. These findings were obtained by a multimodal hybrid microscope, which requires various calibration methods, also in terms of its further use as a tool in a nanorobotic environment. A Scanning Probe…

A Novel Integrated Way for Deciphering the Glycan Code for the FimH Lectin

Eva-Maria Krammer, Julie Bouckaert, Rostyslav Bilyy, Ralf Blossey, Sabine Szunerits, Solomiya Paryzhak, Marc Lensink, Sebastien Gouin, Clarisse Bridot, Tetiana Dumych

The fimbrial lectin FimH from uro- and enteropathogenic Escherichia coli binds with nanomolar affinity to oligomannose glycans exposing Manα1,3Man dimannosides at their non-reducing end, but only with micromolar affinities to Manα1,2Man dimannosides. These two dimannoses play a significantly…

GaN-Based Laser Wireless Power Transfer System

Carlo de Santi, Matteo Meneghini, Alessandro Caria, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Boris Kalinic, Tiziana Cesca, Gaudenzio Meneghesso, Enrico Zanoni

The aim of this work is to present a potential application of gallium nitride-based optoelectronic devices. By using a laser diode and a photodetector, we designed and demonstrated a free-space compact and lightweight wireless power transfer system, whose efficiency is limited by the efficiency of…

Evidence of optically induced degradation in gallium nitride optoelectronic devices

Carlo de Santi, Alessandro Caria, Nicola Renso, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni, Matteo Meneghini

We provide experimental evidence that gallium-nitride-based optoelectronic devices can be affected by a photon-driven degradation mechanism unrelated to catastrophic optical damage. Any role of current in such degradation is excluded by stress tests under laser irradiation in the open-circuit…

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…

An indoor variance-based localization technique utilizing the UWB estimation of geometrical propagation parameters

Brecht Hanssens, David Plets, Emmeric Tanghe, Claude Oestges, Davy Gaillot, M. Lienard, Taoyong Li, Heidi Steendam, Luc Martens, Wout Joseph

A novel localization framework is presented based on Ultra-Wideband (UWB) channel sounding, employing a triangulation method using the geometrical properties of propagation paths, such as time-delay of arrival, angle of departure, angle of arrival, and their estimated variances. In order to extract…

Thermal conductivity of deca-nanometric patterned Si membranes by multiscale simulations

Hayat Zaoui, Pier Luca Palla, Stefano Giordano, Fabrizio Cleri, Maxime Verdier, David Lacroix, J.F. Robillard, Konstantinos Termentzidis, Évelyne Martin

The hollowing of silicon membranes to form a lattice of cylindrical holes, also called phononic crystal, has been used by several experimental groups willing to fabricate efficient thermoelectric modules. The idea is to reduce the thermal conductivity without impacting the electronic conductivity.…
