Structural determination of bilayer graphene on SiC(0001) using synchrotron radiation photoelectron diffraction

I. Razado-Colambo, J. Avila, D. Vignaud, S. Godey, X. Wallart, D P Woodruff, M.C. Asensio

In recent years there has been growing interest in the electronic properties of ‘few layer’ graphene films. Twisted layers, different stacking and register with the substrate result in remarkable unconventional couplings. These distinctive electronic behaviours have been attributed to structural…

Nano-structured top contact with low optical polarization dependence for THz generation using photodiodes

Sara Bretin, Maximilien Billet, Emilien Peytavit, Francois Vaurette, Christophe Coinon, X. Wallart, Jean-Francois Lampin, Malek Zegaoui, Guillaume Ducournau, Mohammed Zaknoune

Uni-travelling carrier photodiode (UTC-PD) with different top optical and electrical accesses are proposed towards optical polarization sensitivity reduction. With the optimized structure, only 1 percent dependence in optical polarization is obtained while ensuring good RF access. Measurements up…

Effective and rapid technique for temporal response modeling of surface acoustic wave interdigital transducers

Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Bogdan Piwakowski, Frédéric Jenot

Surface Acoustic Wave Interdigital Transducers (SAW-IDT) has a considerable application potential for characterization of properties of thin layers, coatings and functional surfaces. For optimization of these SAW-IDTs, it is necessary to study various SAW-IDT configurations by varying the number of…

A time-domain model and experimental validation of the acoustic field radiated by air-coupled transducers

Ji Li, Bogdan Piwakowski

This paper presents a time-domain model for the prediction of an acoustic field in an air-coupled, noncontact, ultrasonic setup, which includes an air-coupled Emitter, the Propagation space and an aircoupled Receiver (EPR). The model takes into account the finite size of the aperture receiver,…
