Low-frequency dynamic drain current modeling in AlGaN-GaN HEMTs

Valeria Di Giacomo, Alberto Santarelli, Fabio Filicori, Antonio Raffo, Giorgio Vannini, Raphaël Aubry, Christophe Gaquière

Low-frequency dispersive effects in AlGaN/GaN HEMTs are here modeled above their cutoff frequencies by adopting a modeling approach developed for GaAs PHEMTs. To this aim, a new identification procedure is proposed, which allows to obtain very accurate predictions of the pulsed drain currents, even…

New results with blind time domain equalization for OFDM system

Sid Ahmed Elahmar, Ali Djebbari, Merahi Bouziani, Jean-Michel Rouvaen

The Multicarrier Equalization by Restoration of RedundancY (MERRY) algorithm has been shown to blindly and adaptively shorten a channel to the length of the guard interval in an OFDM system. Most published works on blind Time Domain Equalization (TEQ) convergence analysis are confined to Ts-spaced…

Energy transfer between semiconductor nanocrystals : validity of Förster's theory

Guy Allan, Christophe Delerue

We theoretically study the energy transfer between semiconductor nanocrystals and we calculate the rate of this process in the case of direct-gap (InAs) and indirect-gap (Si) semiconductors. The calculations are based on the tight-binding method that enables us to determine the transfer rate,…

Ionization energy of donor and acceptor impurities in semiconductor nanowires: importance of dielectric confinement

Mamadou Diarra, Yann-Michel Niquet, Christophe Delerue, Guy Allan

Calculations of the electronic states of donor and acceptor impurities in nanowires show that the ionization energy of the impurities is strongly enhanced with respect to the bulk, above all when the wires are embedded in a material with a low dielectric constant. In free-standing nanowires with…
