Mercury telluride colloidal quantum dots : electronic structure, size-dependent spectra, and photocurrent detection up to 12 µm

Sean E. Keuleyan, Philippe Guyot-Sionnest, Christophe Delerue, Guy Allan

HgTe colloidal quantum dots are synthesized with high monodispersivity with sizes up to ∼15 nm corresponding to a room temperature absorption edge at ∼5 μm. The shape is tetrahedral for larger sizes and up to five peaks are seen in the absorption spectra with a clear size dependence. The size range…

Fabrication et caractérisation DC de composant HEMTs In(Ga)AlN/GaN sur silicium

Léon-Thierry Okala, Marie Lesecq, Philippe Altuntas, Jean-Claude de Jaeger

Cet article présente un procédé de fabrication de transistors HEMTs InAlN/GaN et AlGaN/GaN, en lithographie optique, sur substrat Si(111). Les mesures de Hall et TLM ont permis d'évaluer la résistance de contact, la résistance carrée, la mobilité et la densité de porteurs. La caractérisation…

1 to 220 GHz complex permittivity behavior of flexible polydimethylsiloxane substrate

Pierre-Yves Cresson, Yovan Orlic, Jean-François Legier, Erick Paleczny, Luc Dubois, Nicolas Tiercelin, Philippe Coquet, Philippe Pernod, Tuami Lasri

Coplanar transmission lines (CPW) are realized on polydimethylsiloxane (PDMS) substrate in order to characterize its complex permittivity, from 1 to 220 GHz. By varying the complex permittivity, the propagation constant of the PDMS-CPW calculated with full wave software is matched to those…

Contribution au développement d'un réseau sans fil pour le contrôle santé intégré (CSI) des structures

Laïd Sadoudi, Michael Bocquet, Emmanuel Moulin, Yassin El Hillali, Farouk Benmeddour, Jamal Assaad

L'explosion des technologies sans fil durant la dernière décennie a suscité une quantité importante d'applications couvrant des domaines très variés. Dans le domaine des transports et notamment dans celui du ferroviaire, la suppression des liens filaires permet une couverture…

Active control of a piezoelectric phononic crystal using electrical impedance

Sid Ali Mansoura, Pierre Maréchal, Bruno Morvan, Anne-Christine Hladky, Bertrand Dubus

We consider a one dimensional Phononic Crystal (PC) based on a stack of plates including piezoelectric layers. The model takes into account electrical external circuit connected to the piezoelectric layers with the exception of the layer for which the impedance is evaluated. Only longitudinal waves…

A decision feedback equalizer with channel-dependent power consumption for 60-GHz receiver

Ilias Sourikopoulos, Antoine Frappé, Andreas Kaiser, Laurent Clavier

The design of a baseband decision feedback equalizer, featuring a continuous-time digital delay line, is discussed within the context of a wireless, Line-Of-Sight, communication scenario over the 60-GHz band. BER simulations advocate for a critical-tap cancellation scheme, which leads to the…

Optomechanical interactions in two-dimensional Si and GaAs phoXonic cavities

Said El-Jallal, M. Oudich, Yan Pennec, Bahram Djafari-Rouhani, A. Makhoute, Quentin Rolland, Samuel Dupont, Joseph Gazalet

We investigate theoretically the optomechanical interactions inside cavities created in two-dimensional infinite phoXonic crystals constituted by a square array of holes in silicon (Si) and gallium arsenide (GaAs) matrices. The cavity is simply obtained by removing one hole in the perfect crystal.…

Magneto-transport subband spectroscopy in InAs nanowires

Florian Vigneau, Vladimir Prudkovskiy, Ivan Duchemin, Walter Escoffier, Philippe Caroff, Yann-Michel Niquet, Renaud Leturcq, Michel Goiran, Bertrand Raquet

We report on magnetotransport measurements in InAs nanowires under a large magnetic field (up to 55 T), providing a spectroscopy of the one-dimensional electronic band structure. Large modulations of the conductance mediated by a control of the Fermi energy reveal the Landau fragmentation, carrying…
