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…
