An Opportunistic Reconfiguration Strategy for Environmentally Powered Devices

Giovanni De Micheli, Alexandru Emilian Susu

Environmental energy is becoming a feasible alternative to traditional energy sources for ultra low-power devices such as sensor nodes and smart watches. Moreover, the increas- ing need for exibility and recon gurability of such devices makes its energy ma ...

Préparation et caractérisation de nanoparticules bimétalliques (Pt-Au) sur un substrat en diamant dopé au bore

Bahaa El Roustom

Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...

Impact of inhomogeneous excitonic broadening on the strong exciton-photon coupling in quantum well nitride microcavities

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Gabriel Christmann

GaN/AlGaN and InGaN/GaN quantum wells (QWs) are investigated as the active region for room-temperature strong exciton-photon coupling in high-quality AlInN/(Al)GaN microcavities (MCs). Angular resolved photoluminescence (PL) measurements performed on an Al ...

Multiobjective Optimisation of integrated energy systems for remote communities considering economic and CO2 emissions

Daniel Favrat, Xavier Pelet, Geoffrey Basil Leyland

The methods for designing, planning and managing integrated energy systems, while holistically considering the major economic and environmental factors, are still embryonic. However, the first phase of the design is often crucial if we want to manage resou ...

In surface segregation in InGaN/GaN quantum wells

Nicolas Grandjean

We investigate both theoretically and experimentally the effects of the In surface segregation in InGaN/GaN quantum wells (QWs). It is shown that this phenomenon induces a blue-shift of the QW photoluminescence (PL) energy, which does not depend on the QW ...

Highly Phosphorescence Iridium Complexes and their Application in Organic Light-Emitting Devices

Michael Graetzel, Mohammad Khaja Nazeeruddin, Libero Zuppiroli, Robin Humphry-Baker, Detlef Berner

A new series of iridium(III) mixed ligand complexes TBA[Ir(ppy)2(CN)2] (1), TBA[Ir(ppy)2(NCS)2] (2), TBA[Ir(ppy)2(NCO)2] (3), and [Ir(ppy)2(acac) (4) (ppy = 2-phenylpyridine; acac ...

Two-dimensional "pseudo-donor-acceptor-pairs" model of recombination dynamics in InGaN/GaN quantum wells

Nicolas Grandjean

Recombination dynamics in InGaN/GaN quantum wells has been studied by time resolved photoluminescence (PL). The radiative recombination processes in these systems can be qualitatively explained on a nanometer-scale by a model based on the recombination dyn ...

Carrier-carrier interaction and fast intersubband scattering in wide GaAs quantum wells

Benoît Marie Joseph Deveaud

Wide quantum wells, where the energy spacing between the first two energy levels is lower than the energy of the polar optical phonon, could represent the ideal condition to obtain a population inversion and the production of infrared lasers. On the other ...
