Design guidelines for releasing silicon nanowire arrays by liquid and vapor phase hydrofluoric acid

Vikram Passi, Emmanuel Dubois, Aurélie Lecestre, A. Sanchez-Linde, B. Du Bois, J.P. Raskin

Silicon nanowires of various geometries are fabricated using top-down approach starting from silicon-on-insulator substrate. Arrays of nanowires presenting widths from 25 up to 100 nm regularly spaced by 50 nm up to 1 μm are patterned and released. A comparison of various release methodologies,…

In situ high-temperature characterization of AlN-based surface acoustic wave devices

T. Aubert, Jochen Bardong, Ouarda Legrani, O. Elmazria, M. Badreddine Assouar, Gudrun Bruckner, Abdelkrim Talbi

We report on in situ electrical measurements of surface acoustic wave delay lines based on AlN/sapphire structure and iridium interdigital transducers between 20 °C and 1050 °C under vacuum conditions. The devices show a great potential for temperature sensing applications. Burnout is only observed…

AlN/SI interfaces properties revealed by broadband characterization of coplanar waveguides

Adrien Cutivet, Alain Agboton, Philippe Altuntas, François Lecourt, Marie Lesecq, Nicolas Defrance, Yvon Cordier, Magdalena Chmielowska, Stephanie Rennesson, Julien Camus, Keltouma Aït Aïssa, Laurent Le Brizoual, Mohamed Abdou Djouadi, Jean-Claude de Jaeger, François Boone, Hassan Maher

This paper focuses on the electrical investigation of various AlN/Si interfaces by means of broadband characterization and modeling of CPW (coplanar waveguide) for frequencies up to 50 GHz. These electric measurements are performed under different biases and temperatures in order to investigate the…

Legendre and Laguerre polynomial approach for modeling of wave propagation in layered magneto-electro-elastic media

Olivier Bou Matar, Noura Gasmi, Huan Zhou, M. Goueygou, Abdelkrim Talbi

A numerical method to compute propagation constants and mode shapes of elastic waves in layered piezoelectric-piezomagnetic composites, potentially deposited on a substrate, is described. The basic feature of the method is the expansion of particle displacement, stress fields, electric and magnetic…

Multiple exciton generation and ultrafast exciton dynamics in HgTe colloidal quantum dots

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

The investigation of sub-nanosecond exciton dynamics in HgTe colloidal quantum dots using ultrafast transient absorption spectroscopy is reported. The transmittance change spectrum acquired immediately after pumping is dominated by a bleach blue-shifted by ∼200–300 nm from the photoluminescent…
