Design and radiation hardness of next generation solar UV radiometers

Samuel Gissot, Ali Benmoussa, Boris Giordanengo, Ali Soltani, Terubumi Saito, Udo Schühle, Udo Kroth, Alexander Gottwald

For next space-based ultraviolet (UV) solar radiometers, we propose a design based on subsystem components that are selected according to lessons learned from previous flying missions and ground irradiation campaigns. UV interference filters inherited from space-based solar missions show strong...

Graphene nanotransistors for RF charge detection

E. Pallecchi, Q. Wilmart, A.C. Betz, S.H. Jhang, G. Fève, J.M. Berroir, Sylvie Lepilliet, Gilles Dambrine, H. Happy, B. Plaçais

We have studied the static and dynamical properties of a graphene microwave nanotransistor to be used as sensitive fast charge detectors. The channel consists of exfoliated graphene on SiO2 with a 120 nm long, 900-1500 nm wide top-gate deposited on 5 nm AlOx dielectric. The scattering parameters...

UV and IR laser induced ablation of Al2O3/SiN:H and a-Si:H/SiN:H

T. Schutz-Kuchly, A. Slaoui, J. Zelgowski, A. Bahouka, M. Pawlik, Jean-Pierre Vilcot, E. Delbos, M. Bouttemy, R. Cabal

Experimental work on laser induced ablation of thin Al2O3(20 nm)/SiN:H (70 nm) and a-Si:H (20 nm)/SiN:H (70 nm) stacks acting, respectively, as p-type and n-type silicon surface passivation layers is reported. Results obtained using two different laser sources are compared. The stacks are...

ZnO nanowires and PbS quantum dots for third-generation solar cells

Basma El Zein, Mutalifu Abulikemu, Erkki Alarousu, Omar F. Mohammed, Enrico Traversa, El Hadj Dogheche

Nanowires and quantum dots hold promising potency to enhance the performance of solar cells by improving light absorption, light trapping, exciton generation, and photoexcited-carrier collection. Quantum dot sensitized solar cells consist of three components: semiconductor quantum dots, one...

A decision feedback equalizer with channel-dependent power consumption for 60-GHz receiver

Ilias Sourikopoulos, Antoine Frappé, Andreas Kaiser, Laurent Clavier

The design of a baseband decision feedback equalizer, featuring a continuous-time digital delay line, is discussed within the context of a wireless, Line-Of-Sight, communication scenario over the 60-GHz band. BER simulations advocate for a critical-tap cancellation scheme, which leads to the...

Efficient reduction of thermal conductivity in silicon using phononic-engineered membranes

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

Phononic crystals (PC) have been a remarkably active research field for more than two decades [1]. The principle of Bragg reflection on an artificial crystal-like structure leading to additional spectral (band gaps) and refractive (negative refraction, anisotropy) properties is scalable in any...

Optical properties of HgTe nanocrystals

Guy Allan, Christophe Delerue, Ali Al-Otaify, David J. Binks, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach

HgTe nanocrystals presently receive growing interest because the negative band gap in bulk HgTe enables tunability of the gap from the infrared to the near infrared in quantum dots thanks to the quantum confinement. Therefore we propose a tight-binding model of HgTe which gives an accurate band...
