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...

High-definition television transmission at 600 GHz combining THz photonics hotspot and high-sensitivity heterodyne receiver

Guillaume Ducournau, Fabio Pavanello, Alexandre Beck, L. Tohme, S. Blin, P. Nouvel, Emilien Peytavit, Mohamed Zaknoune, P. Szriftgiser, Jean-Francois Lampin

A 600 GHz data transmission using the combination of a photonic emission using a uni-travelling carrier photodiode and an electronic detection is investigated. A high-definition television transmission at this carrier frequency with a very low power at the receiver is reported. Only 10 nW of...

Ferroelectrics based absorbing layers

Jianping Hao, Véronique Sadaune, Ludovic Burgnies, Didier Lippens

We show that ferroelectrics-based periodic structure made of BaSrTiO3 (BST) cubes, arrayed onto a metal plate with a thin dielectric spacer film exhibit a dramatic enhancement of absorbance with value close to unity. The enhancement is found around the Mie magnetic resonance of the Ferroelectrics...

All optical method for investigation of spin and charge transport in semiconductors : combination of spatially and time-resolved luminescence

Fabian Cadiz, Philippe Barate, D. Paget, Denis S Grebenkov, J.P. Korb, A.C.H. Rowe, Thierry Amand, S. Arscott, Emilien Peytavit

A new approach is demonstrated for investigating charge and spin diffusion as well as surface and bulk recombination in unpassivated doped semiconductors. This approach consists in using two complementary, conceptually related, techniques, which are time-resolved photoluminescence (TRPL) and...

Graphene nanotransistors for RF charge detection

E. Pallecchi, Q. Wilmart, A.C. Betz, S.H. Jhang, G. Fève, J.M. Berroir, Sylvie Lepilliet, Gilles Dambrine, H. Happy, B. Plaçais

We have studied the static and dynamical properties of a graphene microwave nanotransistor to be used as sensitive fast charge detectors. The channel consists of exfoliated graphene on SiO2 with a 120 nm long, 900-1500 nm wide top-gate deposited on 5 nm AlOx dielectric. The scattering parameters...

Modeling of GaN Schottky diodes

Chong Jin, Etienne Okada, Marc Faucher, Damien Ducatteau, Mohamed Zaknoune, Dimitris Pavlidis

GaN-based Schottky diodes for microwave, millimeter-wave power applications were characterized and modeled. The modeling technique employed dummy structure to derive parasitic elements introduced by access pads. Intrinsic elements were extracted by fitting junction capacitance for fixed grading...

Robust receiver in impulsive noise

Xin Yan, Laurent Clavier, Ido Nevat, Gareth W. Peters, François Septier

Impulsive interference is a strong limitation in ultra wide band systems or ad hoc networks. Using stochastic geometry without considering a guard zone around the receiver leads to an alpha-stable distribution for this interference. Based on this assumption, it is possible to design efficient...
