Low work function thin film growth for high efficiency thermionic energy converter : coupled Kelvin probe and photoemission study of potassium oxide

François Morini, Emmanuel Dubois, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki

Recent researches in thermal energy harvesting have revealed the remarkable efficiency of thermionic energy converters comprising very low work function electrodes. From room temperature and above, this kind of converter could supply low power devices such as autonomous sensor networks. In this...

Carbohydrate-lectin interaction on graphene-coated surface plasmon resonance (SPR) interfaces

Abra Penezic, Geetanjali Deokar, Dominique Vignaud, Emmanuelle Pichonat, Henri Happy, Palaniappan Subramanian, Blaženka Gasparovic, Rabah Boukherroub, Sabine Szunerits

The paper describes the detection of carbohydrate- lectin interaction on graphene-on-metal surface plasmon resonance (SPR) interfaces. Graphene-coated gold-based SPR interfaces were formed through the transfer of large-area graphene grown by chemical vapor deposition (CVD) on polycrystalline Cu...

Sub-THz characterisation of multi-walled carbon nanotube thin films using vector network analyser

S. Puthukodan, E. Dadrasnia, V.K.T. Vinod, H.K. Nguendon, H. Lamela, Guillaume Ducournau, Jean-Francois Lampin, F. Garet, J.L. Coutaz, D.M. Lee, S. Baik

A vector network analyser is used to study the electrical properties of multi-walled carbon nanotube (MWCNT) thin films deposited on a fused quartz substrate in the sub-terahertz (THz) frequency ranges of 220-325 GHz (WR3.4) and 325-500 GHz (WR2.2). The experiment is performed in free space. The...

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....

Electro-optic and converse-piezoelectric properties of epitaxial GaN grown on silicon by metal-organic chemical vapor deposition

Mireille Cuniot-Ponsard, Irma Saraswati, S.M. Ko, Mathieu Halbwax, Y.H. Cho, El Hadj Dogheche

We report the measurement of the (r13, r33) Pockels electro-optic coefficients in a GaN thin film grown on a Si(111) substrate. The converse piezoelectric (d33) and electro-absorptive coefficients are simultaneously determined. Single crystalline GaN epitaxial layers were grown with a AlGaN buffer...

Enhanced efficiency by the effect of strain on the structure of a solar cell

Abdelkader Aissat, Rachid Bestam, M. El Bey, Jean-Pierre Vilcot

This paper is expected at the study of Ga1-xInxP/GaAs based solar cell. The effects of indium concentration, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the Ga1-xInxP/GaAs structure were investigated. We noticed that for higher...

Hypersonic band gap in an AlN-TiN bilayer phononic crystal slab

S. Hemon, Abdellatif Akjouj, A. Soltani, Yan Pennec, Y. El Hassouani, Abdelkrim Talbi, V. Mortet, Bahram Djafari-Rouhani

We show both theoretically and experimentally the existence of a complete band gap in a phononic crystal (PnC) constituted by periodical air holes drilled in a solid bi-layer slab. The composite slab is formed with an aluminum nitride (AlN) layer deposited on a titanium nitride (TiN) thin metallic...
