Confinement and losses of THz planar Goubau lines fabricated on a thin silicon substrate

Abdallah Chahadih, Mokhtar Zehar, Abbas Ghaddar, S. Kaya, Ibrahim Türer, Gabriel Moreno, Y. Zapart, Tahsin Akalin

Low loss broad band transmission lines are of great interest for terahertz applications. To overcome high losses, Planar Goubau Lines (PGL) have been designed and fabricated on high resistivity silicon substrate. The measured loss level is typically 1dB/mm around 250GHz. The transitions are also…

Low loss microstrip transmission-lines using cyclic olefin copolymer COC-substrate for sub-THz and THz applications

Abdallah Chahadih, Magdalena Chudzik, Israel Arnedo, Abbas Ghaddar, Ivan Arregui, Fernando Teberio, Aintzane Lujambio, Miguel A. G. Laso, Txema Lopetegi, Tahsin Akalin

We describe low loss microstrip transmission line with compact coplanar waveguide transitions for sub-terahertz application. The conducting transmission line is fabricated on the surface of a thin cyclic olefin copolymer dielectric layer. A vector network analyzer (VNA) has been used to obtain the…

Temperature and damping effects on the frequency dependence of electrostatic force microscopy force gradients

R. Arinero, J. Trasobares, Pascal Girard, M. Ramonda, N. Clément

In this paper we demonstrate that depending on the surrounding ambient, which may be manifested by different damping conditions, a "bump" in frequency response of Electric Force Microscope (EFM) cantilevers may be observed, either in electrical amplitude or phase signals of AC gradients.…

Design and simulation of Cd1-xZnxTe thin films epitaxied on CdTe substrate for photovoltaic devices applications

A. Aissat, M. Fathi, Jean-Pierre Vilcot

This work concerns the study and the simulation of a structure containing II-VI semiconductor for photovoltaic application. We studied the influence of the zinc concentration on the various parameters of the alloy Cd1-xZnxTe epitaxied on a CdTe substrate. Indeed, the insertion of zinc increases the…

How imperfect interfaces affect the nonlinear transport properties in composite nanomaterials

F. Pavanello, S. Giordano

Nanomaterials composed of a population of particles dispersed in a matrix represent the building block for the next generation of several technologies: energy storage and conversion, thermal management, electronics, and photovoltaics. When interfaces between particles and matrix are imperfect, the…

Acoustic wave localization in one-dimensional Fibonacci phononic structures with mirror symmetry

Anne-Christine Hladky, Jerome O. Vasseur, S. Degraeve, C. Granger, M. de Billy

This paper reports on numerical and experimental results of acoustic transmission spectra of bead chains with symmetric and asymmetric Fibonacci-like structures. As a matter of comparison, perfect periodic acoustic waveguide structures are also examined. This study shows that Fibonacci structures…

A crown-ether loop-derivatized oligothiophene doubly attached on gold surface as cation-binding switchable molecular junction

T.K. Tran, K. Smaali, M. Hardouin, Q. Bricaud, M. Oçafrain, P. Blanchard, S. Lenfant, S. Godey, J. Roncali, D. Vuillaume

A crown-ether dithiol quaterthiophene is synthesized and immobilized on gold surface by double covalent fixation. UV-vis spectroscopy and cyclic voltammetry show that the corresponding dithioester precursor can complex Pb2+ in solution and that this property is maintained for monolayers of the…
