Influence of the semi-conductor layer thickness on electrical performance of staggered n- and p-channel organic thin-film transistors

Autor: Mohammed Benwadih, Jean-Marie Verilhac, Isabelle Chartier, R. Coppard, Romain Gwoziecki, Stéphane Altazin, Gilles Horowitz, G. Le Blevennec, Damien Boudinet

Publikováno v: Organic Electronics. 11:291-298

In this study, we report on the influence of the semi-conductor thickness on organic thin-film transistors (OTFTs). Devices are fabricated with a top gate/bottom contact geometry on plastic substrates. Both n-channel and p-channel OTFTs made, respect

Magneto Elastic Modes in Ferro or Ferrimagnetic Polycristals

Autor: I. Brard, G. Le Blevennec

Publikováno v: Journal de Physique IV Proceedings
Journal de Physique IV Proceedings, EDP Sciences, 1997, 07 (C1), pp.C1-191-C1-192. ⟨10.1051/jp4:1997170⟩

We propose a new method to compute the dimensional variations of ferri or ferro magnetic materials induced by an electromagnetic wave. The algorithm used derives from a mechanical finite element method to solve stress and strain states of a solid. Ma

First-principles investigations of the electronic, optical and chemical bonding properties of SnO2

Autor: G. Le Blevennec, Samir F. Matar, Ph. Barbarat

Publikováno v: Journal of Materials Chemistry. 7:2547-2550

The electronic structure of the rutile-type oxide SnO2 is examined self-consistently using the augmented-spherical-wave (ASW) method within the density-functional theory (DFT). The influence of hybridization between the different l-states on the chem

Detection limits for nanoparticles in solution with classical turbidity spectra

Autor: G. Le Blevennec

Publikováno v: SPIE Proceedings.

Detection of nanoparticles in solution is required to manage safety and environmental problems. Spectral transmission turbidity method has now been known for a long time. It is derived from the Mie Theory and can be applied to any number of spheres,

Tunable luminescence properties of AgInS2-ZnS and AgInS2-ZnS@ZnS particles

Autor: G. Le Blevennec, Frédéric Chandezon, S. De Sousa Nobre, Théo Chevallier

Publikováno v: SPIE Proceedings.

Luminescent nanocrystals of AgIn S 2-ZnS (ZAIS) and core-shell AgInS 2 -ZnS@ZnS (ZAIS@ZnS) nanostructures were synthesized with different compositions of the core AgInS2-ZnS solid solution. With this method, luminophores displaying a broad emission s
