Low-Operating-Voltage Organic Transistors Made of Bifunctional Self-Assembled Monolayers

M. Mottaghi, P. Lang, F. Rodriguez, Anna Rumyantseva, Abderrahim Yassar, G. Horowitz, S. Lenfant, D. Tondelier, D. Vuillaume

Self-assembled monolayers (SAMs) are molecular assemblies that spontaneously form on an appropriate substrate dipped into a solution of an active surfactant in an organic solvent. Organic field-effect transistors are described, built on an SAM made of bifunctional molecules comprising a short alkyl…

Critical temperatures of 70%Pb(Mg1∕3Nb2∕3)O3–30%PbTiO3 thin films investigated by dielectric, ferroelectric, and structural measurements

X.J. Meng, Denis Remiens, Mickael Detalle, B. Dkhil, Jl. Sun, Jh. Chu

The authors have investigated the temperature dependence of the ferroelectric, dielectric, and structural properties of 70%Pb(Mg1∕3Nb2∕3)O3–30%PbTiO3 thin films. Two critical temperatures were evidenced. The first one occurring around 410K corresponds to the bulk paraelectric-ferroelectric phase…

Integrated terahertz TEM horn antenna

Emilien Peytavit, Jean-Francois Lampin, Tahsin Akalin, L. Desplanque

A terahertz transverse electromagnetic horn antenna (THz-TEMHA) monolithically integrated on a gallium arsenide substrate has been studied by means of subpicosecond pulses generated and measured on a 50 Ω coplanar waveguide. The measured reflection coefficient is below −10 dB from 100 GHz to about…

Analyse physique et thermique des structures TLM AlGaN/GaN

Brahim Benbakhti, Michel Rousseau, Ali Soltani, Jean-Claude de Jaeger

Pour les applications de puissance, la puissance dissipée dans un composant à base de GaN devient trèssignificative et par conséquent produit un effet d’auto-échauffement très important. L’auto-échauffement dans lecomposant augmente considérablement la température de réseau et donc dégrade les…

Emission characteristics of ion-irradiated In0.53Ga0.47As based photoconductive antennas excited at 1.55 µm

Juliette Mangeney, Nicolas Chimot, L. Meignien, Nicolas Zerounian, Paul Crozat, Karine Blary, Jean-Francois Lampin, Patrick Mounaix

We present a detailed study of the effect of the carrier lifetime on the terahertz signal characteristics emitted by Br+-irradiated In0.53Ga0.47As photoconductive antennas excited by 1550 nm wavelength femtosecond optical pulses. The temporal waveforms and the average radiated powers for various…
