A 200-GHz true E-mode low-noise MHEMT

Hassan Maher, Ikram El Makoudi, Peter Frijlink, Derek Smith, Marc Rocchi, S. Bollaert, Sylvie Lepilliet, Gilles Dambrine

In this paper, a fully passivated true enhancement mode 110-nm metamorphic high-electron mobility transistor (E-MHEMT) on GaAs substrate with excellent dc and RF performance has been developed. By choosing an indium content of 40% for the AlInAs/GalnAs/AlInAs MHEMT, the difference between the...

Synchronization over rapidly time-varying multipath channel for CDMA downlink RAKE receivers in Time-Division mode

Eric Pierre Simon, Laurent Ros, Kosai Raoof

In this paper, we consider a Time-Division CDMA system operating in downlink mode in a multi-user multipath channel scenario. In order to implement RAKE reception, delays, phases and magnitudes of the different paths need to be estimated and the estimates updated. In the context of burst...

Etude et réalisation d'une source térahertz accordable de grande pureté spectrale, Study and realisation of a CW high spectral purity tuneable THz Source

Romain Czarny

La génération d'onde THz de grande pureté spectrale par photomélange est une technique très prometteuse afin de réaliser des oscillateurs locaux THz performants. Nous avons donc proposé une approche originale consistant à associer un laser bi-fréquence émettant autour de 1 µm à un..., Continuous high-purity THz generation through photomixing is a very promising technique for future THz local oscillators. Consequently, we have proposed an innovative photomixing architecture based on a dual frequency laser emitting around 1 µm associated with a matched band gap photoconductor....

Molecular dynamics simulation of the recrystallization of amorphous Si layers: Comprehensive study of the dependence of the recrystallization velocity on the interatomic potential

Christophe Krzeminski, Quentin Brulin, Valérie Cuny, Emmanuel Lecat, Évelyne Martin, Fabrizio Cleri

The molecular dynamics method is applied to simulate the recrystallization of an amorphous/crystalline silicon interface. The atomic structure of the amorphous material is constructed with the method of Wooten, Winer, and Weaire. The amorphous on crystalline stack is annealed afterward on a wide...
