MIMO and diversity techniques in tunnels

M. Lienard, Pierre Degauque, J.M. Molina-Garcia-Pardo, C. Sanchis-Borras

To improve the performances of a communication link, both in terms of capacity and bit error rate, MIMO technique is a solution which has been widely studied. However, in road or railway tunnels, the waves are guided by the structure and the angular spread of the rays, both at the transmitting side…

1900 V, 1.6 mΩ cm2 AlN/GaN-on-Si power devices realized by local substrate removal

Nicolas Herbecq, Isabelle Roch-Jeune, Nathalie Rolland, Domenica Visalli, Joff Derluyn, Stefan Degroote, Marianne Germain, F Medjdoub

We demonstrate a high-voltage low on-resistance AlN/GaN/AlGaN double heterostructure grown by metal-organic chemical vapor deposition on a silicon (111) substrate using a total buffer thickness of less than 2 μm. A fully scalable local substrate removal technique was developed to dramatically…

Architectures supramoléculaires sur la surface de Si(111)-B

Younes Makoudi, Judicaël Jeannoutot, Matthieu Beyer, Bulent Baris, B. Grandidier, Frank Palmino, Frédéric Cherioux

La formation des réseaux supramoléculaires périodiques à grande échelle sur une surface est d'un intérêt primordial pour le développement de composants intelligents [1]. Cet objectif nécessite la synthèse des molécules organiques ayant des fonctions appropriées en vue d'obtenir des…

Scale effects induced by imperfect interfaces in nanomaterials transport properties

Fabio Pavanello, F. Manca, Pier Luca Palla, Evelyne Lampin, Fabrizio Cleri, Stefano Giordano

One of the crucial factors governing the physical properties of nanomaterials is the complex behavior of the interfaces[1]. While at the macroscopic level their specific role is usually neglected, in nanostructured systems the properties of the contact between phases have to be carefully defined.…
