Phononic engineering of silicon using "dots on the fly" e-beam lithography and plasma etching

Valeria Lacatena, Maciej Haras, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki, Emmanuel Dubois

Nowadays, the interest in reducing the lattice thermal conductivity (kL), without affecting the electrical one (ke), represents one of the main objectives for researchers in thermoelectricity. In semiconductors, lattice vibrations contribute about 95% to thermal conductivity. Because phonons and…

1 to 220 GHz complex permittivity behavior of flexible polydimethylsiloxane substrate

Pierre-Yves Cresson, Yovan Orlic, Jean-François Legier, Erick Paleczny, Luc Dubois, Nicolas Tiercelin, Philippe Coquet, Philippe Pernod, Tuami Lasri

Coplanar transmission lines (CPW) are realized on polydimethylsiloxane (PDMS) substrate in order to characterize its complex permittivity, from 1 to 220 GHz. By varying the complex permittivity, the propagation constant of the PDMS-CPW calculated with full wave software is matched to those…

Room-temperature quantum spin Hall effect in HgTe honeycomb superlattices

Cristiane Morais Smith, Wouter Beugeling, Efterpi Kalesaki, Yann-Michel Niquet, Christophe Delerue, Daniel Vanmaekelbergh

The recent experimental realization of self-assembled honeycomb superlattices of truncated semiconducting nanocrystals has opened a new path to engineer graphene-like structures. Atomistic band-structure calculations for honeycomb lattices of PbSe and CdSe have shown a rich band structure, with…

Simultaneous confinement of light and sound in the same cavity generates a strong phonon-photon interaction, known as optomechanical (OM) coupling. Several optomechanical systems provided already proof of concept demonstrations for enhanced telecommunication devices and sensors. And using OM…

Etude de l'influence de la pointe sur les mesures KFM sur échantillon d'AlGaAs/GaAs

Sylvain Pouch, Nicolas Chevalier, Denis Mariolle, François Triozon, Thierry Melin, Lukasz Borowik

La microscopie à sonde de Kelvin (KFM) est capable de fournir une mesure résolue spatialement et en énergie de la structure de bande en surface d'un matériau. Elle dépend néanmoins fortement des propriétés physiques de la pointe utilisée, propriétés pouvant être la largeur de l'apex, la…

Integrated measurement platform for thermal conductivity measurements in thin-film crystalline silicon and silicon-germanium

Maciej Haras, Valeria Lacatena, Stéphane Monfray, J.F. Robillard, Thomas Skotnicki, Emmanuel Dubois

Thermoelectric conversion requires materials with low thermal conductivity k high electrical conductivity s and thermopower P. Performance of thermoelectric material is evaluated by the zT=P^2sT/k figure-of-merit. Bi2Te3 or Sb2Te3 are usually used near room temperature but they are harmful,…

Phosphorus-hyperdoped Si nanocrystals : a model for localized surface plasmon resonance

X. Pi, Christophe Delerue

It has been recently realized that semiconductor nanocrystals can be doped with point defects or impurities up to a very high level, sometimes above the bulk solubility limit. In parallel, hyperdoping has also emerged as a promising means to change the electrical and optical properties of Si. In…
