On the effect of δ-doping in self-switching diodes

Andreas Westlund, Ignacio Iñiguez-De-La-Torre, Per-Åke Nilsson, Tomas González, Javier Mateos, Paul Sangaré, Guillaume Ducournau, Christophe Gaquière, L. Desplanque, Xavier Wallart, Jan Grahn

Lowering the carrier concentration is presented as a way to considerably improve the performance of self-switching diode (SSD) detectors. A physics-based theoretical model was used to derive an expression for the responsivity of SSDs as a function of carrier concentration, mobility, and design...

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...

Acousto-optical tunable transmissive grating beam splitter

Anthony Dieulangard, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

We present a tunable transmissive grating beam splitter for multiple laser line separation based on acousto-optic interaction in tellurium dioxide. Acousto-optic devices are well known for light modulation, frequency shifting, filtration or deflection. For a deflector, the incident light beam is...

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...

On Popularization of Scientific Education In Italy Between 12th And 16th Centuries

Raffaele Pisano, Paolo Bussotti

Mathematics education is also a social phenomenon because it is influenced both by the needs of the labour market and by the basic knowledge of mathematics necessary for every person to be able to face some operations indispensable in the social and economic daily life. Therefore the way in which...
