Spatial terahertz modulator

Zhenwei Xie, Xinke Wang, Jiasheng Ye, Shengfei Feng, Wenfeng Sun, Tahsin Akalin, Yan Zhang

Terahertz (THz) technology is a developing and promising candidate for biological imaging, security inspection and communications, due to the low photon energy, the high transparency and the broad band properties of the THz radiation1,2,3. However, a major encountered bottleneck is lack of…

Joint channel and phase noise estimation in OFDM systems at very high speeds

Jin Fang, Eric Pierre Simon, Marion Berbineau, M. Lienard

In this paper, the problem of joint phase noise and channel estimation for OFDM systems over a fast time-varying frequency-selective channel is explored. Each channel tap time-variation within one OFDM symbol is approximated by a Basis Expansion Model (BEM). Joint estimation is performed on…

Exploring electronic structure of one-atom thick polycrystalline graphene films : a nano angle resolved photoemission study

J. Avila, I. Razado, S. Lorcy, R. Fleurier, E. Pichonat, D. Vignaud, X. Wallart, M.C. Asensio

The ability to produce large, continuous and defect free films of graphene is presently a major challenge for multiple applications. Even though the scalability of graphene films is closely associated to a manifest polycrystalline character, only a few numbers of experiments have explored so far…

Ultrafast optical technique for measuring the electrical dependence of the elasticity of piezoelectric thin film : demonstration on AlN

Arnaud Devos, P. Emery, E. Defay, N. Ben Hassine, G. Parat

We present a technique based on ultrafast acoustics which permits us to measure the electrical dependence of the elastic properties of a thin piezoelectric layer. Ultrafast acoustics offers a unique way of measuring elastic properties of thin-layer in a non-destructive way using ultrashort optical…

Modelling Of Supramolecular Network Deposited On A Semiconductor Surface

Guillaume Copie, Christophe Krzeminski, Fabrizio Cleri, Younes Makoudi, B. Grandidier, Frédéric Cherioux, Frank Palmino

We investigated the self-assembly mechanisms and electronic properties of highly- symmetric organic molecules based on a substituted 1,2,5-tri(4-phenyl)benzene core[1], deposited on a passivated boron-doped Si(111)-√3x√3 R30° surface, by using ab-initio calculations, empirical molecular dynamics…

Laser ultrasonics and mode conversion for flaw depth gauging

Frédéric Faëse, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy, Mohamed Ourak

Compared to earliest non destructive testing and evaluation methods based on transducers, laser ultrasonics shows specific advantages. It is a non-contact method combining a high spatial resolution and a large bandwidth, allowing high temperature and/or geometrically complex materials testing. In…
