Terahertz wireless communication using GaAs transistors as detectors

L. Tohme, S. Blin, Guillaume Ducournau, P. Nouvel, D. Coquillat, S. Hisatake, T. Nagatsuma, A. Pénarier, L. Varani, W. Knap, Jean-Francois Lampin

The detection of high data-rate wireless communication using a terahertz- frequency carrier, and a GaAs transistor as a detector, is reported. Communications are investigated around 0.2 and 0.3087 THz. For the first time, an error-free transmission at data rates up to 8.2 Gbit/s is demonstrated,…

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…

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…

Surface asymmetry of coated spherical nanoparticles

Amélie H.R. Koch, Gaëtan Lévêque, Sebastian Harms, Karmena Jaskiewicz, Max Bernhardt, Andreas Henkel, Carsten Sönnichsen, Katharina Landfester, George Fytas

We validate the nonspherical grafting arrangement of isotropically coated spherical nanoparticles as very recently proposed. We utilize localized surface plasmon resonance enhanced dynamic polarized and depolarized light scattering from Au nanoparticles, the spherical symmetry of which was revealed…

On-wafer differential noise figure measurement without couplers on a vector network analyzer

Yogadissen Andee, Alexandre Siligaris, Francois Graux, Francois Danneville

This papers presents a measurement technique for the noise figure of on-wafer differential amplifiers using 4-port network analyzers. The approach is based on the determination of the correlation of output noise waves in terms of the 4-port S-parameters and of the output noise powers. The…
