Physical study of the dissipated power area in high electron mobility transistors for thermal modelling

Brahim Benbakhti, Michel Rousseau, Jean-Claude de Jaeger

The hot area in power transistors due to the power dissipation is determined from a 2D-hydrodynamic model. The power is calculated everywhere in the device from the knowledge of the physical quantities (current density, electric field). The hot area is determined accurately to be coupled to a…

Comparison of structural and electrical properties of PMN-PT films deposited on Si with different bottom electrodes

M. Detalle, Gang Wang, Denis Remiens, P. Ruterana, P. Roussel, B. Dkhil

PMN-PT (70/30) thin films were deposited by sputtering on silicon substrate covered with different bottom electrodes: TiOx/Pt and LaNiO3 (LNO). The bilayers TiOx/Pt are deposited by sputtering and the LNO layer by sol–gel. Whatever the bottom electrodes the perovskite phase appears at 400 °C; the…

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…

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,…

All-optical tunability of InGaAsP/InP microdisk resonator by infrared light irradiation

Maxime Beaugeois, Bernard Pinchemel, Mohamed Bouazaoui, Marie Lesecq, Sophie Maricot, Jean-Pierre Vilcot

We report the optical characterization of an InP structure constituted by waveguides coupled to microcavity disk resonators. The lateral waveguide confinement is obtained by deep reactive ion etching through the guiding layer. We demonstrate the possibility of tuning optically the resonance…
