Electrowetting at a liquid metal-oxide-semiconductor junction

S. Arscott

A voltage polarity dependent, voltage-induced wetting transition is demonstrated using a liquid metal-oxide-semiconductor (MOS) junction. A droplet of mercury can be made to spread out on an oxidized silicon wafer upon the application of a voltage. The wetting is seen to depend on the doping type…

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…

The Faraday threshold in small cylinders and the sidewall non-ideality

William R. Batson, Farzam Zoueshtiagh, Raviprasad Narayanan

In this work we investigate, by way of experiments and theory, the Faraday instability threshold in cylinders at low frequencies. This implies large wavelengths where effects from mode discretization cannot be ignored. Careful selection of the working fluids has resulted in an immiscible interface…

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…

Surface plasmons in coaxial metamaterial cables

M.S. Kushwaha, Bahram Djafari-Rouhani

Thanks to Victor Veselago for his hypothesis of negative index of refraction, metamaterials – engineered composites – can be designed to have properties difficult or impossible to find in nature: they can have both electrical permitivity (ǫ) and magnetic permeability (µ) simultaneously negative.…

Time-reversal UWB positioning beacon for railway application

B. Fall, F. Elbahhar, M. Heddebaut, Atika Rivenq

This paper studies a new positioning beacon for railway transport using Ultra Wideband (UWB) radio and Time Reversal (TR) techniques. UWB radio has the potential to offer a good level of performance in terms of localization accuracy. Time Reversal channel pre-filtering facilitates signal detection…

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…
