Optimized ohmic contacts for InAlGaN/GaN HEMTs

Farah Bouazzaoui, Marie Pierre Chauvat, Magali Morales, Malek Zegaoui, F Medjdoub, Piero Gamarra, Slawomir Kret, Pierre Ruterana

During the last years, the most significant improvement of the contact resistance forAlInN/GaN high electron mobility has been the use of a highly doped n+ GaN layer grown bymolecular beam epitaxy for the source and drain terminals. In a first report [1], the ohmiccontact processing was carried out…

Improved Eigenfilter Design Method for Channel Shortening Equalizer in TH-UWB

Noureddine Benamara Benotmane, Sid Ahmed Elahmar, Iyad Dayoub, Walaa Hamouda

The large delay spread of ultra-wideband (UWB) channels causes intersymbol interference and therefore increases the complexity of a UWB Rake receiver. To resolve these problems, we present a new method for the design of channel shortening equalizers (CSE) in time-hopping UWB systems. Our proposed…

Checksum-Filtered List Decoding Applied to H.264 and H.265 Video Error Correction

Firouzeh Golaghazadeh, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

The latest video coding standards, H.264 and H.265, are highly vulnerable in error-prone networks. Reconstructed packets may exhibit significant degradation in terms of peak signal-to-noise ratio and visual quality. This paper presents a novel list-decoding approach exploiting the receiver side…

Graphene Doping Induced Tunability of Nanoparticles Plasmonic Resonances

Rana Nicolas, Gaëtan Lévêque, Pierre-Michel Adam, Thomas Maurer

Interest in graphene has been widely increasing since its discovery in 2004. Research on graphene for plasmonic applications has also boomed due to the high potential of these systems. In this article, we discuss the possible interaction between metallic NPs and graphene monolayer. We show how the…

Modeling and optimization of core (p-GaN)-multishell (i-InxGa1-xN/i-GaN/n-Al0.1Ga0.9N /n-GaN) nanowire for photovoltaic applications

Abdelkader Aissat, Fethi Benyettou, Isabelle Berbezier, Jean-Pierre Vilcot

In this work we report a modeling and optimization of a novel core (p-GaN)-multishell (i-InxGa1-xN/i-GaN/n-Al0.1Ga0.9N/n-GaN) coaxial NWs with a total length of about 3 μm and a radius of 0.19 μm. The variation of Indium composition in the i-InxGa1-xN active layer shows that x = 15% is the optimal…
