Optical waveguiding properties into porous gallium nitride structures investigated by prism coupling technique

Bandar Alshehri, Seung-Min Lee, Jin-Ho Kang, Su-Hyun Gong, Sang-Wan Ryu, Yong-Hoon Cho, El Hadj Dogheche

In order to modulate the refractive index and the birefringence of Gallium Nitride (GaN), we have developed a chemical etching method to perform porous structures. The aim of this research is to demonstrate that optical properties of GaN can be tuned by controlling the pores density. GaN films are…

Effect of interface configurations on the dynamic scaling behavior of Pb(Zr0.53Ti0.47)O3 thin films

Kui Li, Nossikpendou Sama, Tao Li, Denis Remiens, Gang Du, Xianlin Dong, Genshui Wang

The ferroelectric hysteresis and the scaling relations of hysteresis area ⟨A⟩ against field amplitude E and frequency f in Pb(Zr0.53Ti0.47)O3 thin films using platinum and LaNiO3 (LNO) as both bottom and top electrodes were systematically investigated. Interestingly, it was found that the influence…

Transport properties of CdSe nanocrystal superlattice

Pierre Capiod, Maxime Berthe, B. Grandidier, Wiel Evers, Daniel Vanmaekelbergh

Two-dimensional materials exhibit exotic electronic properties and high specific surface areas that make them unique to investigate novel physical phenomena. In addition, their two-dimensional geometry is directly compatible with established design and processing approaches from the semiconductor…

Multi-carrier transmission of vectorial modulation schemes using electronic transceivers at 588 GHz

Guillaume Ducournau, P. Szriftgiser, D. Bacquet, Mohammed Zaknoune, Rédha Kassi, Jean-Francois Lampin

A reported is presented on the first communication system using vectorial modulation schemes above 500 GHz. Using Schottky-based electronic technologies at 588 GHz, potentialities of high-level multicarrier modulation schemes for wireless links are analysed. The wireless link is composed of an…

Silicon nanotweezers inside liquid for the real time characterization of DNA degradation under radiotherapy treatment

Grégoire Perret, T. Lacornerie, V. Kumemura, N. Lafitte, H. Guillou, L. Jalabert, E. Lartigau, T. Fujii, Fabrizio Cleri, H. Fujita, Dominique Collard

Tumor cell killing by γ-ray beams in radiotherapy is currently based on a rather empirical understanding of the basic mechanisms and effectiveness of DNA damage by radiation. On the other hand, the mechanical behavior of DNA, e.g., sequence-sensitivity, elastic vs. plastic response, is well…

Micro-nanostructured silicon based superomniphobic surfaces

Thi Phuong Nhung Nguyen, Rabah Boukherroub, V. Thomy, Yannick Coffinier

We report on the fabrication of silicon nanostructured superhydrophobic and superoleophobic surfaces also called "superomniphobic" surfaces. For this purpose, silicon interfaces with different surface morphologies, single or double scale structuration, were investigated. These structured…
