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…

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…

Demonstrating kHz frequency actuation for conducting polymer microactuators

Ali Maziz, Cedric Plesse, Caroline Soyer, Claude Chevrot, Dominique Teyssié, Eric Cattan, Frederic Vidal

This paper reports results on ionic EAP micromuscles converting electrical into micromechanical response in open-air. Translation of small ion motion into large deformation in bending microactuator and its amplifi cation by fundamental resonant frequency are used as tools to demonstrate that small…

Angle-dependent ray tracing simulations of reflections on pyramidal textures for silicon solar cells

Vincent Magnin, Joseph Harari, Mathieu Halbwax, S Bastide, D Cherfi, Jean-Pierre Vilcot

Pyramidal textures are commonly used to reduce reflections from silicon solar cells and improve light absorption by light trapping. They are generally modelled or characterized under normal incidence. In this work, a monolayer 3D ray tracing program taking into account the polarisation of light…

PbS quantum dots and ZnO nanowires for 3rd generation solar cells

Basma El Zein, El Hadj Dogheche, Enrico Traversa

Semiconductor nanostructures with low dimensions such as quantum dots and nanowires are considered as important building blocks for the third generation solar cells, due to their useful optical and electrical properties. Quantum dots and nanowires hold promising potency to improve the performance…

Synthesis and electrical characterisations of a low work function cesium oxide coating for high efficiency thermionic energy converter

François Morini, J.F. Robillard, Stéphane Monfray, I.D. Baikie, Thomas Skotnicki, Emmanuel Dubois

One main challenge associated with solid-state thermoelectric materials is to combine electron-crystal electrical conductivity and phonon-glass thermal properties that are difficult to conciliate. A markedly different principle of thermoelectric conversion is based on the micro-thermionic generator…

Scanning tunneling microscopy of GaAs/GaAsSb nanowires

Adrian Díaz Álvarez, Pierre Capiod, Maxime Berthe, Tao Xu, Jean-Philippe Nys, Isabelle Lefebvre, Philippe Caroff, Philipp Ebert, B. Grandidier

Understanding surface structure and surface composition is of particular importance for semiconductor nanowire applications, since they might strongly contribute to the electrical, optical and thermal properties of the Nanowires. A prototypical material is GaAs, where polytype inclusions consisting…
