Sara Bretin

Les communications aux fréquences terahertz sont étudiées dans un contexte de transmissions en espace libre. L’objectif de la thèse est de proposer une étude comparative de différentes topologies d’électrodes supérieures appliquées aux photodiodes UTC ainsi qu’un module d’intégration de ces…, The terahertz frequency communications are studied in a context of free space transmissions. The objective of this thesis is to propose a comparative study of different topologies of top electrode applied to UTC photodiode and a module for packaging this type of components. Those components permit…

NanoSIMS imaging of D/H ratios on FIB sections

Dan Lévy, Jérôme Aléon, Alice Aléon-Toppani, David Troadec, Rémi Duhamel, Adriana Gonzalez-Cano, Hélène Bureau, Hicham Khodja

The D/H ratio imaging of weakly hydrated minerals prepared as Focused Ion Beam (FIB) sections is developed in order to combine isotopic imaging by Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS) of micrometer-sized grains with other nanoscale imaging techniques, such as Transmission Electron…

Linearity and robustness evaluation of 150-nm AlN/GaN HEMTs

Mehdi Rzin, Matteo Meneghini, Fabiana Rampazzo, Veronica Gao Zhan, Carlo de Santi, Riad Kabouche, Malek Zegaoui, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

We report on linearity and robustness of AlN/GaN HEMTs with ultra-thin 4nm AlN barrier for millimeter wave range applications. Static and dynamic I-V characteristics feature high peak transconductance (gmpeak) of 385 mS/mm, and the transconductance exhibits small changes with gate bias. Semi on-…

Buffer breakdown in GaN-on-Si HEMTs: a comprehensive study based on a sequential growth experiment

Matteo Borga, Matteo Meneghini, Davide Benazzi, Eleonora Canato, Roland Püsche, Joff Derluyn, Idriss Abid, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

The aim of this work is to investigate the breakdown mechanisms of the layers constituting the vertical buffer of GaN-on-Si HEMTs; in addition, for the first time we demonstrate that the breakdown field of the AlN nucleation layer grown on a silicon substrate is equal to 3.2 MV/cm and evaluate its…

Optimizing heat harvesting in a membrane based planar µTEG: modelling and fabrication, & vice versa

Zahia Bougrioua, Ibrahim Bel-Hadj, Katir Ziouche

Micro-thermoelectric generators (µTEGs) are energy harvesting solutions to supply power for autonomous microsystems and other miniature applications. Based on a preliminary modeling we designed original all-Silicon µTEGs with a planar configuration in which the heat to harvest flows in-plane of a…

Electrocaloric effect in Pb_0.3Ca_xSr_0.7-xTiO₃ ceramics near room temperature

Liuyang Han, Shao-Bo Guo, Shi-Guang Yan, Denis Remiens, Gen-Shui Wang, Xian-Lin Dong

The electrocaloric (EC) effect is strongly related to interaction of polarization and temperature changes, showing great potential in high-efficient solid state refrigeration. This work focuses on the Pb_0.3Ca_xSr_0.7-xTiO<sub>…

Influence of doping level and surface states in tunneling spectroscopy of an In_0.53Ga_0.47As quantum well grown on p-type doped InP(001)

Nathali Alexandra Franchina Vergel, A. Tadjine, V. Notot, M. Mohr, A. Kouassi N’guissan, Christophe Coinon, Maxime Berthe, Louis Biadala, K. Sossoe, M. Dzagli, J.-C. Girard, Guillemin Rodary, L. Desplanque, R. Berndt, D. Stievenard, X. Wallart, Christophe Delerue, B. Grandidier

A steplike density of states is the hallmark of a two-dimensional electron gas. Here, scanning tunneling spectroscopy is used to investigate this property in the differential conductance of an In0.53Ga0.47As quantum well grown on p-type doped InP(001). We show that the appearance of a steplike…
