Progressive multi-layer drop-casting of CdSe nanoparticles for photocurrent down shifing monitoring

Yannick Lambert, Di Zhou, Tao Xu, Odile Cristini, D. Deresmes, B. Grandidier, D. Stievenard

We investigated the spectroscopic photocurrent response of photovoltaic devices versus an increasing number of drop-casted CdSe nanoparticles onto planar and nanocones silicon p-i-n junctions. For all samples, a strong enhancement of the photocurrent in the UV range was detected as well as a…

Pavlov's dog associative learning demonstrated on synaptic-like organic transistors

O. Bichler, W. Zhao, F. Alibart, S. Pleutin, S. Lenfant, D. Vuillaume, C. Gamrat

In this paper we present an original demonstration of an associative learning neural network inspired by the famous Pavlov’s dogs experiment. A single nanoparticle organic memory field effect transistor (NOMFET) is used to implement each synapse. We show how the physical properties of this dynamic…

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…

Gain of spatial diversity techniques in tunnel environment

M. Lienard, Jose Maria Molina-Garcia-Pardo, Pierre Degauque, Davy Gaillot

It is well known that diversity techniques improve the signal to noise ratio and are thus widely used both for SIMO or MIMO configurations. Their performances, described in the literature, are based on the assumption of a Rayleigh or Rice fading distribution of the electric field. However, in…

Phase Coded Costas Signals for Ambiguity Function Improvement and Grating lobes Suppression

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Atika Rivenq

In this paper, a novel radar signal is proposed. It is based on a modification of Costas signals obtained by increasing the frequency separation of Costas frequency hops beyond the orthogonality condition. Indeed, Costas codes are well known for their good Range-Doppler properties. Their…

Focused ion beam Ga3+ for the realization of piezoelectric PZT nano structures

Denis Remiens

Piezoelectric nano-structures (islands of dimensions in the lateral size range 50-500 nm) have been fabricated by Focused Ga3+ Ion Beam (FIB) etching on PbZr0.54Ti0.46O3 thin films obtained by magnetron sputtering. The degradation induced by the etching process is investigated through the evolution…

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…
