Tight-binding calculations of the optical response of optimally P-doped Si nanocrystals : a model for localized surface plasmon resonance

Xiaodong Pi, C. Delerue

We present tight-binding calculations in the random-phase approximation of the optical response of Silicon nanocrystals (Si NCs) ideally doped with large concentrations of phosphorus (P) atoms. A collective response of P-induced electrons is demonstrated, leading to localized surface plasmon…

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…

Negative refraction of acoustic waves using a foam-like metallic structure

Anne-Christine Hladky, Jerome O. Vasseur, G. Haw, Charles Croënne, L. Haumesser, A.N. Norris

A phononic crystal (PC) slab made of a single metallic phase is shown, theoretically and experimentally, to display perfect negative index matching and focusing capability when surrounded with water. The proposed PC slab is a centimeter scale hollow metallic foam-like structure in which acoustic…

A 1 GHz SAW oscillator on epitaxial GaN/Si substrate : toward co-integrated frequency sources

M. Faucher, G. Martin, J.M. Friedt, S. Ballandras

GaN is an attractive material for the fabrication of various integrated devices combining several physical effects (semi-conductors, piezoelectric and optic parts, etc.). This work is dedicated to the investigation of GaN for the fabrication of surface acoustic wave oscillators. The first…
