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…

Performance evaluation of ultra-low frequency underwater acoustic projectors

Bertrand Dubus, Pascal Mosbah, Jean-Rémi Hartmann, Jacky Garcin

Ultra Low Frequency (ULF) underwater waves can travel great distance and are generally used in sonar or oceanography. To generate these waves, underwater transducers, utilized in the 10-400 Hz frequency range, have radiating surfaces whose dimensions are small with respect to the acoustic…

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…

Contribution of the buffer layer to the Raman spectrum of epitaxial graphene on SiC(0001)

F. Fromm, M.H. Oliveira, A. Molina-Sanchez, M. Hundhausen, J.M.J. Lopes, H. Riechert, L. Wirtz, T. Seyller

We report a Raman study of the so-called buffer layer with (6√3 × 6√3)R30◦ periodicity which forms the intrinsic interface structure between epitaxial graphene and SiC(0001). We show that this interface structure leads to a nonvanishing signal in the Raman spectrum at frequencies in the range of…

High quality factor mg-scale silicon mechanical resonators for 3-mode optoacoustic parametric amplifiers

F.A. Torres, P. Meng, L. Ju, C. Zhao, D.G. Blair, K.-Y. Liu, S. Chao, M. Martyniuk, Isabelle Roch-Jeune, R. Flaminio, C. Michel

Milligram-scale resonators have been shown to be suitable for the creation of 3-mode optoacoustic parametric amplifiers, based on a phenomena first predicted for advanced gravitational-wave detectors. To achieve practical optoacoustic parametric devices, high quality factor resonators are required…
