Doped semiconductor nanocrystal junctions

Lukasz Borowik, Thuat Nguyen-Tran, Pere Roca I Cabarrocas, Thierry Melin

Semiconductor junctions are the basis of electronic and photovoltaic devices. Here, we investigate junctions formed from highly doped (ND 1020 1021cm 3) silicon nanocrystals (NCs) in the 2-50 nm size range, using Kelvin probe force microscopy experiments with single charge sensitivity. We show that...

Electronic structure and transport properties of Si nanotubes

J. Li, T. Gu, C. Delerue, Y.M. Niquet

The electronic structure and the transport properties of Si nanotubes with outer diameter between 2 and 20 nm are investigated using fully atomistic simulations. A formula is given for the energy of the band edges versus diameter and thickness. The phonon-limited mobility of electrons and holes is...

Surface states and conductivity of silicon nano-wires

U.K. Bhaskar, T. Pardoen, V. Passi, J.P. Raskin

The transport characteristics of low dimensional semiconductors like silicon nano-wires (SiNWs) rarely conform to expectations from geometry and dopant density, exhibiting significant variations as a function of different surface terminations/conditions. The association of these mechanisms with...

Conformal antenna array for 60 GHz applications

Vasili Semkin, Mikko Kyrö, Veli-Matti Kolmonen, Cyril Luxey, Aimeric Bisognin, Fabien Ferrero, Henri Happy, Antti V. Räisänen

In this work, the design of a millimeter-wave conformal antenna array for cylindrical structure is developed. Antenna array consists of 4x4 elements and operates at 60 GHz. Different substrates and their properties are considered. Fiber Teflon substrate was chosen for the antenna structure due to...

AlGaN/GaN HEMTs on HR silicon substrate (111) with an AlN seed film grown by PVD

Philippe Altuntas, N. Defrance, Marie Lesecq, Adrien Cutivet, Alain Agboton, Yvon Cordier, Magdalena Chmielowska, Stephanie Rennesson, Julien Camus, Keltouma Aït Aïssa, Laurent Le Brizoual, Mohamed Abdou Djouadi, Jean-Claude de Jaeger

AlGaN/GaN HEMTs on silicon substrates have been fabricated and their static and small-signal RF characteristics investigated. The AlGaN/GaN material structures were grown on (111) p-Si by LP-MOVPE. Devices exhibit a saturation current of 0.91 A/mm, a good pinchoff and a peak extrinsic...

The effects of increasing antenna arrays and spatial correlation on loading algorithm for closed-loop MIMO vehicle-to-infrastructure communications

Imade Fatani, Mohamed Gharbi, François-Xavier Coudoux, Marion Berbineau, Patrick Corlay, Marc G. Gazalet

In this paper, an efficient bit-loading algorithm in the context of SVD-aided MIMO transmission for vehicle-to-infrastructure (V2I) communications is presented. This algorithm, which exploits the intrinsic properties of the eigen-channels resulting from SVD, tries to minimize the error probability...
