Inkjet printed flexible transmission lines for high frequency applications up to 67 GHz

Mohamed Moez Belhaj, Wei Wei, Emiliano Pallecchi, Colin Mismer, Isabelle Roch-Jeune, Henri Happy

This letter introduces radio frequency(RF) characterization of ink-jet printed coplanar waveguides (CPW) with and without strain. Kapton is selected as flexible substrate with different sintering temperature. With optimized inkjet printing parameters, well defined patterns with high resolution...

From semiconductor nanocrystals to artificial graphene and topological insulator

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

Recent advancements in colloidal chemistry indicate that two-dimensional single-crystalline sheets of semiconductors forming a honeycomb lattice can be synthesized from semiconductor nanocrystals [1]. We perform atomistic tight-binding calculations of the band structure of CdSe sheets with such a...

Theory of self-assembled nanoparticle networks as logic building blocks

Fabrizio Cleri, Sergio Carrillo, Christophe Krzeminski

Recently, self-assembled networks of functionalized nano particles (NPSAN) were proposed as a prototype of innovative devices [1], with switchable NP-NP links. Thanks to the chemical properties of the surface molecules, these would ultimately show memristive behaviour, as building blocks of a...

Electro-optic and converse piezoelectric coefficients of epitaxial thin films : GaN grown on Si, and (Sr,Ba)Nb2O6 (SBN) grown on Pt coated MgO (poster)

Mireille Cuniot-Ponsard, Irma Saraswati, Suk-Min Ko, Mathieu Halbwax, Yong-Hoon Cho, El Hadj Dogheche

We report the first measurement of the (r13, r33) Pockels electro-optic coefficients in a SBN thin film and in a GaN thin film grown on silicon. The converse-piezoelectric and electro-absorptive coefficients are simultaneously determined.

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...
