Inhibition of interface pollution in AlGaN/GaN HEMT structures regrown on semi-insulating GaN templates

M. Azize, Z. Bougrioua, P. Gibart

AlGaN/GaN high-electron mobility transistors (HEMTs) structures regrown by metalorganic vapour phase epitaxy (MOVPE) on semi-insulating (SI) GaN templates, after exposure to air, results in the presence of parasitic conducting channels at regrowth interface. Air contamination of the SI GaN...

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...
