Atomistic simulation of plasticity in silicon nanowires

F. Cleri, T. Ishida, D. Collard, H. Fujita

We study the tensile deformation of polycrystalline Si nanowires by means of molecular dynamics simulations. The initial microstructure is composed by a network of nanocrystals glued together by a thin layer of amorphous material. Atomistic simulations could clearly identify liquidlike flow in the…

High efficiency optoelectronic terahertz sources

Jean-Francois Lampin, Emilien Peytavit, Tahsin Akalin, Guillaume Ducournau, Francis Hindle, Gaël Mouret

We have developed a new generation of optoelectronic large bandwidth terahertz sources based on TEM horn antennas monolithically integrated with several types of photodetectors: low-temperature grown GaAs (LTG-GaAs) planar photoconductors, vertically integrated LTG-GaAs photoconductors on silicon…

Terahertz photomixers based on ultra-wideband horn antennas, Photomélangeurs térahertz à antennes cornet ultra-large bande

Alexandre Beck, Tahsin Akalin, Guillaume Ducournau, Emilien Peytavit, Jean-Francois Lampin

We review recent advances in the development of new terahertz photomixers based on the integration of an ultrafast photodetector with an ultra-wideband transverse electromagnetic wave horn antenna. We expose first a simplified theory of this antenna, the choice of the dimensions and the results of…, Cet article expose le développement récent d'une nouvelle génération de photomélangeurs térahertz basés sur l'intégration d'un photodétecteur ultra-rapide avec une antenne ultra-large bande de type cornet à onde transverse électromagnétique. Nous exposons d'abord la théorie…
