Confinement-modulated junctionless nanowire transistors for logic circuits

François Vaurette, Renaud Leturcq, Sylvie Lepilliet, Bruno Grandidier, Didier Stiévenard

We report the controlled formation of nanoscale constrictions in junctionless nanowire field-effect transistors that efficiently modulate the flow of the current in the nanowire. The constrictions act as potential barriers and the height of the barriers can be selectively tuned by gates, making the…

A real-time terahertz beam monitoring application with a 1024-pixel CMOS terahertz camera module

Richard Al Hadi, Jean-Francois Lampin, Ullrich Pfeiffer

In this paper a terahertz beam monitoring application of an optically pumped molecular terahertz laser with a 1024-pixel CMOS terahertz camera is presented. The terahertz camera has been used to detect variations in real-time of the terahertz source beam around 2.52 THz.

Step-conformal deposition of TiO2 and MnO2 electrodes on advanced silicon microstructures for 3D Li-ion microbatteries and micro-supercapacitors

Étienne Eustache, Camille Douard, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Thierry Brousse, Christophe Lethien

To get autonomous smart microsystem, a miniaturized power source should be integrated. As the device is surface limited, the energy and power performances of commercially available planar microbatteries and micro-supercapacitors are not sufficient to reach this goal. To improve their performances…

Acousto-optic couplings in two-dimensional lithium niobate phoxonic crystal

Quentin Rolland, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

We investigate the acousto-optic couplings in two-dimensional infinite piezoelectric phoXonic crystal cavities. The periodic structure considered consists in a square array of air inclusions drilled in Lithium Niobate matrix. This structure allows the simultaneous confinement of acoustic and optic…

Train accurate localization using ultra wide band radio and time reversal

Bouna Fall, Fouzia Elbahhar, Marc Heddebaut, Atika Rivenq

In guided transport, the precise localization of trains is vital for nominal operation of the transport system. In a propagation environment such as a railway line, an effective localization sensor is complex to design since it must operate in the presence of many fixed and mobile obstacles…

Pulse compression waveforms design and Cross-ambiguity processing for Radar applications

Nadjah Touati, Charles Tatkeu, Atika Rivenq, Yassin El Hillali, Thierry Chonavel

Radar waveforms design is an important step to design a hole radar system. In this paper, several waveforms based on modified Costas codes are used. The properties and performances are tested and compared. We propose a detection based on cross-ambiguity calculation for these waveforms. Indeed, such…

PbS quantum dots and ZnO nanowires for 3rd generation solar cells

Basma El Zein, El Hadj Dogheche, Enrico Traversa

Semiconductor nanostructures with low dimensions such as quantum dots and nanowires are considered as important building blocks for the third generation solar cells, due to their useful optical and electrical properties. Quantum dots and nanowires hold promising potency to improve the performance…
