Ultra-short pulsed laser for nano-texturation associated to plasma immersion implantation for 3D shallow doping : Application to silicon photovoltaic

Halbwax M., Sarnet T., Delaporte Ph., Sentis M., Etienne H., Torregrosa F., Vervisch V., Martinuzzi S., LP3 UMR CNRS 6182, FR

It has been shown in a recent past (Mazur et al) that a simple way to improve the silicon-based solar cells low efficiency (around 20%) is to irradiate the silicon surface with a series of [...]

Near-Field Raman and Luminescence Spectroscopies to evidence chemical heterogeneity of surfaces with sub-wavelength spatial resolution

Humbert B., Grausem J., Dossot M., Cremel S., LCPME UMR 7564 CNRS-UHP, FR

Near-field scanning optical microscopy (NSOM or SNOM) offers the opportunity to collect optical information at a spatial scale well below the diffraction limit. Using a silica fiber tip coated with aluminum and having a small [...]

Explicit Short Channel Compact Model of Independent Double Gate Mosfet

Reyboz M., Rozeau O., Poiroux T., Martin P., Cavelier M., Jomaah J., CEA-LETI, FR

This paper describes an explicit short channel compact model of Independent Double Gate (IDG) MOSFET with undoped channel. The validity of this model is demonstrated by comparison with Atlas simulations. The model was implemented in [...]

Compact modeling of drain current in Independently Driven Double-Gate MOSFETs

Munteanu D., Autran J-L, Loussier X., Tintori O., L2MP-CNRS, FR

As CMOS scaling is approaching its limits, Double-Gate (DG) MOSFET is envisaged as a possible alternative to the conventional bulk MOSFET. In spite of excellent electrical performances due to its multiple conduction surfaces, conventional DG [...]

Simulation of ac-electroosmotic flows for concentration of particles on biosensors

Tanguy L., Casalis G., Nicu L., LAAS/CNRS, FR

Artificial concentration of particles in a fluid is a major challenge for micro- and nanobiosensors to enhance sensitivity and to reduce the time of response. We present here a numerical simulation of electroosmotic flows for [...]

On the stability length of fluid/liquid interfaces sustained by microfabricated pillars

Berthier J., Man Tran Van, Jeanson H., Sarrut N., CEA-LETI, FR

We focus here on the transfer and concentration of macromolecules from a flowing carrier fluid to a storage liquid. These liquids are flowing in parallel channels, separated by interfaces sustained by micro-pillars. The two fluids [...]

Electrical equivalent circuit for air and liquid characterization of a multilayer micromembrane with piezoelectric actuation and read-out capabilities

Alava T., Ayela C., Nicu L., Laboratory for Analysis and Architecture of systems LAAS-CNRS, FR

In the field of piezoelectric-based resonators, micromembranes have revealed substantial advantages especially for biosensing experiments. To ease the design of new-membrane-based biosensors, an analytical model is crucial. We have elaborated such a model for the [...]
