Dirac cones, topological edge states, and nontrivial flat bands in two-dimensional semiconductors with a honeycomb nanogeometry

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

We study theoretically two-dimensional single-crystalline sheets of semiconductors that form a honeycomb lattice with a period below 10 nm. These systems could combine the usual semiconductor properties with Dirac bands. Using atomistic tight-binding calculations, we show that both the atomic…

Measurement of the thermal conductivity of polydimethylsiloxane polymer using the three omega method

Nadine Al-Khudary, Pierre-Yves Cresson, Yovan Orlic, Philippe Coquet, Philippe Pernod, T. Lasri

Polydimethylsiloxane (PDMS) has widely appeared in different electronic and medical applications. The knowledge of the thermal properties of PDMS and especially its thermal conductivity is required while processing PDMS to design a particular device. In this paper measurement of the thermal…

Dispersion properties and low infrared optical losses in epitaxial AlN on sapphire substrate in the visible and infrared range

Ali Soltani, Arnaud Stolz, Joël Charrier, Maghnia Mattalah, Jean-Claude Gerbedoen, Hassan Ali Barkad, Vincent Mortet, Michel Rousseau, Nour Eddine Bourzgui, Ali Benmoussa, Jean-Claude de Jaeger

Optical waveguiding properties of a thick wurtzite aluminum nitride highly [002]-textured hetero-epitaxial film on (001) basal plane of sapphire substrate are studied. The physical properties of the film are determined by X-ray diffraction, atomic force microscopy, microRaman, and photocurrent…

Extension of the crosstalk cancellation method in ultrasonic transducer arrays from the harmonic regime to the transient one

Abdelmajid Bybi, Sébastien Grondel, Jamal Assaad, Anne-Christine Hladky

This paper describes a procedure to extend the crosstalk correction method presented in a previous paper [A. Bybi, S. Grondel, J. Assaad, A.–C. Hladky-Hennion, M. Rguiti, Reducing crosstalk in array structures by controlling the excitation voltage of individual elements: a feasibility study,…

Acousto-optic couplings in two-dimensional lithium niobate phoxonic crystal

Quentin Rolland, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

We investigate the acousto-optic couplings in two-dimensional infinite piezoelectric phoXonic crystal cavities. The periodic structure considered consists in a square array of air inclusions drilled in Lithium Niobate matrix. This structure allows the simultaneous confinement of acoustic and optic…

Confinement-modulated junctionless nanowire transistors for logic circuits

François Vaurette, Renaud Leturcq, Sylvie Lepilliet, Bruno Grandidier, Didier Stiévenard

We report the controlled formation of nanoscale constrictions in junctionless nanowire field-effect transistors that efficiently modulate the flow of the current in the nanowire. The constrictions act as potential barriers and the height of the barriers can be selectively tuned by gates, making the…

Caractérisation en bruit hyperfréquences de transistors bipolaires à hétérojonction SiGe:C avancés jusque 170 GHz

Marina Deng, Sylvie Lepilliet

Les mesures de bruit hyperfréquences sont essentielles pour établir ou conforter un modèle utilisé en vue du design de circuits RF ou millimétriques. Ce papier expose une méthodologie de mesures de bruit, avec des résultats sur transistors bipolaires à hétérojonction SiGe:C jusqu'à 170 GHz, et…
