Determination of the electrostatic lever arm of carbon nanotube field effect transistors using Kelvin force microscopy

David Brunel, D. Deresmes, Thierry Melin

We use Kelvin force microscopy (KFM) to study the electrostatic properties of single-walled carbon nanotube field effect transistor devices (CNTFETs) with backgate geometry at room temperature. We show that KFM maps recorded as a function of the device backgate polarization enable a complete…

A High Mobility Field-Effect Transistor as an Antenna for sub-THz Radiation

Maciej Sakowicz, Jerzy Łusakowski, Krzysztof Karpierz, Marian Grynberg, Wojciech Gwarek, Stephane Boubanga Tombet, Dominique Coquillat, Wojciech Knap, Andrey Shchepetov, S. Bollaert

The experiments on radiation coupling to field effect transistors working as terahertz radiation detectors are reported. Two types of high electron mobility transistors: InGaAs/InAlAs and GaAs/AlGaAs, with different layout geometries are studied. We show that terahertz radiation coupling efficiency…

Applicability of acoustic noise correlation for structural health monitoring in nondiffuse field conditions

Emmanuel Moulin, Najib Abou Leyla, Jamal Assaad, Sébastien Grondel

Ambient noise correlation offers an elegant way of passively caracterize a medium. The principle is that in diffuse field condition, Green’s function between two sensors can be retrieved from the cross-correlated received signals. Here, the technique is applied in conditions where convergence…

Channel estimation of OFDM system for high data rate communications on mobile environments

Boudali Ouarzazi, Marion Berbineau, Iyad Dayoub, Atika Rivenq

One of the main challenges of the 4th generation wireless systems is to provide high data rates in mobile environments. In these 4G products, WiMax (worldwide interoperability for microwave access) and LTE (long term evolution) will be the platform technologies. The rapid development of the…

A simple method for measuring Si-Fin sidewall roughness by AFM

X.H. Tang, V. Bayot, N. Reckinger, D. Flandre, J.P. Raskin, Emmanuel Dubois, B. Nysten

The gate oxide reliability and the electrical behavior of FinFETs are directly related to the surface characteristics of the fin vertical sidewalls. The surface roughness of the fin sidewalls is one of the most important structural parameters to be monitoredin order to optimize the fin patterning…

Defect modes in one-dimensional anisotropic photonic crystal

Noama Ouchani, Driss Bria, Bahram Djafari-Rouhani, Abdlekarim Nougaoui

We theoretically analyze the defect states in a single-defect photonic crystal composed of anisotropic dielectric materials. This structure can trap light of a given frequency range and filter only a certain frequency light. It is shown that the defect modes appear as peaks in the transmission…
