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…

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…

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…

Non-destructive Evaluation of Concrete Damages of Containment Walls in Nuclear Power Plants

Zoubir Medhi Sbartaï, Vincent Garnier, Cedric Payan, Bogdan Piwakowski, E. Larose, J. Saliba, Narintsoa Ranaivomanana, Jean-Paul Balayssac

This paper is focused on the part of the project ANR ENDE that concerns the damage and crack characterization by means of NDT. The tests are done in 3 or 4 points bending in order to study the cracks' generation, their propagation, as well as their opening and closing. The main ultrasonic…

Effect of cobalt addition on the corrosion behavior of near equiatomic NiTi shape memory alloy in normal saline solution: electrochemical and XPS studies

Nawal Alqarni, Joanna Wysocka, Nader El-Bagoury, Jacek Ryl, Mohammed Amin, Rabah Boukherroub

The electrochemical and corrosion (uniform and localized) behavior of a binary Ni52Ti48 shape memory alloy (SMA) and two ternary Ni52Ti48−xCox (x = 1.5 and 4.0 wt%) SMAs were studied. Measurements were conducted in 0.9% NaCl solution at 37 °C employing various electrochemical methods. These include…
