Optimization of photoswitch constituted of a coplanar line introducing an interdigitated MSM photodetector

Abdelkader Aissat, M. El Besseghi, Didier Decoster

In this paper we present the optimization of photoswitches constituted of a coplanar line introducing interdigitated MSM photodetectors in the central strip. The reflection and the transmission coefficients are studied with the aim of highlighting the influence of different geometrical parameters…

Near-field Microwave Microscopy for Liquid Characterization

Sijia Gu, Kamel Haddadi, Tuami Lasri

A near-field microwave microscopy platform for the characterization of liquids is proposed. The technique is based on the association of a network analyzer and an evanescent microwave coaxial probe. The major feature of the system proposed is the development of a broadband tunable matching network…

Electrooptic and converse-piezoelectric properties of epitaxial GaN/Si structures for optoelectronic applications

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

In order to take advantage in all-optic optoelectronic devices, we have investigated the optical and piezoelectric properties of GaN films deposited on (111) silicon. Films are epitaxially grown by MOCVD, thanks to a buffer made of (Al, Ga) N intermediate layers [1]. Structural properties of GaN…

Theoretical and experimental investigation of Lamb waves characteristics in AlN/TiN and AlN/TiN/NCD composite membranes

Ali Soltani, Abdelkrim Talbi, J-C Gerbedoen, Jean-Claude de Jaeger, Philippe Pernod, V. Mortet, A. Bassam

In this study, we present a theoretical and experimental investigations of the zero order quasi-symmetric (S0) Lamb waves mode propagating in AlN/TiN and AlN/TiN/NCD composite membranes. Theoretical analysis of S0 mode characteristics shows that The AlN/TiN membrane enables to achieve smooth…

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…

Young's modulus extraction of epitaxial heterostructure AlGaN/GaN for MEMS application

Achraf Ben Amar, Marc Faucher, Virginie Brandli, Yvon Cordier, Didier Theron

This paper presents a Young's modulus extraction method for thin film group III-nitrides materials such as GaN, AlN, and its ternary AlGaN. The AlGaN/GaN heterostructures are grown by molecular beam epitaxy on Si (111) substrate and designed for MEMS applications. Various cantilevers with a…

Preparation and study of 2-D semiconductors with Dirac type bands due to the honeycomb nanogeometry

Efterpi Kalesaki, Mark Pieter Boneschanscher, Jaco J. Geuchies, Christophe Delerue, Cristiane Morais Smith, Wiel H. Evers, Guy Allan, Thomas Altantzis, Sara Bals, Daniel Vanmaekelbergh

The interest in 2-dimensional systems with a honeycomb lattice and related Dirac-type electronic bands has exceeded the prototype graphene. We show that atomically coherent honeycomb superlattices of rocksalt (PbSe, PbTe) and zincblende (CdSe, CdTe) semiconductors can be obtained by nanocrystal…
