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…

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…

Influence of an interfacial AlxIn1-xSb layer on the strain relaxation and surface morphology of thin GaSb layers epitaxially grown on GaAs(001)

Mathieu Danoy, Pierre-François Angry, Julien Gavrel, Charlène Brillard, L. Desplanque, Y. Wang, P. Ruterana, Xavier Wallart

This work focuses on the strain relaxation and surface morphology of 10 ML thick GaSb layers on GaAs. It is shown that full relaxation is never reached for this thickness. The use of an AlSb interfacial layer only slightly improves strain relaxation but greatly reduces surface roughness. Finally,…

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…

Enhancement of thermoelectric power factor in NaxCoO2/Au multilayers

Xiaohui Zhao, Haifeng Wang, Shufang Wang, El Hadj Dogheche, Jianglong Wang, Guangsheng Fu

NaxCoO2/Au thin film multilayers, with a thickness of the Au layer of 0.5–12 nm, have been fabricated on c-Al2O3 by post annealing of the CoO/Au thin film multilayers in Na vapor at high temperature in air. X-ray diffraction measurements revealed that the resulting NaxCoO2 layer was c-axis oriented…

Modeling and evaluation of power transmission of flapping wing nano air vehicle

Alexandre Bontemps, Sébastien Grondel, Thomas Vanneste, Samuel Dupont, Eric Cattan

In the last decade researchers pursued the development of tiny flying robots inspired by natural flyers. Within this context our main objective is to devise a flying robot-mimicking insect in terms of kinematics and scale using MEMS technologies. For this purpose, an original design has been…
