Numerical and experimental investigation of kerf depth effect on high-frequency phased array transducer

Jin-Ying Zhang, Wei-Jiang Xu, Julien Carlier, X.M. Ji, S. Queste, Bertrand Nongaillard, Y.P. Huang

Background High-frequency ultrasonic transducer arrays are essential for high resolution imaging in clinical analysis and Non-Destructive Evaluation (NDE). However, the structure design and fabrication of the kerfed ultrasonic array is quite challenging when very high frequency (⩾100 MHz) is…

THz surface plasmon modes on planar Goubau lines

Djamal Gacemi, Juliette Mangeney, Thibault Laurent, Jean-Francois Lampin, Tahsin Akalin, Karine Blary, Aloyse Degiron, Paul Crozat, Fanqi Meng

The dispersion relation and confinement of terahertz surface plasmon modes propagating along planar Goubau lines are studied using guided-wave time domain spectroscopy. We demonstrate the radial nature of the surface plasmon mode known as the Goubau mode and the transverse confinement of the…

Level repulsion and evanescent waves in sonic crystals

V. Romero-Garcia, Jerome O. Vasseur, Anne-Christine Hladky, Lluis Miquel Garcia-Raffi, J.V. Sanchez-Perez

This work theoretically and experimentally reports the evanescent connections between propagating bands in periodic acoustic materials. The complex band structures obtained by solving for the k(ω) problem reveal a complete interpretation of the propagation properties of these systems. The…

The transverse electromagnetic horn antenna as an efficient THz pulse emitter

Jean-Francois Lampin, Emilien Peytavit, Tahsin Akalin, Guillaume Ducournau, Jens Klier, Sabine Wohnsiedler, Joachim Jonuscheit, René Beigang

We have fabricated a new photoconductive antenna based on a transverse electromagnetic horn and low temperature grown GaAs. It has been tested with a time-domain terahertz setup. The horn was used as the emitter and a standard dipole photoconductive antenna was used as the receiver. The spectrum…

Optimization of carrier multiplication in quantum dots for more efficient solar cells

Christophe Delerue, Guy Allan

Reviewing recent theoretical works, we propose a strategy to optimize the carrier multiplication in semiconductor quantum dots. This strategy is discussed using calculations on quantum dots of a semi-metal, α-Sn.

Depuis les premiers travaux publiés en 2004, le graphène est obtenu par trois principales techniques, l'exfoliation, le dépôt chimique en phase vapeur et la graphitisation du carbure de silicium. Seules les deux dernières sont adaptées aux technologies standards de la microélectronique. Une…, Since the first publications in 2004, three techniques are mainly used to grow graphene, exfoliation, chemical vapor deposition and graphitization on silicon carbide. Only the two latter ones are suitable with microelectronics technological processes. In this thesis, another method of growth is…
