Ferroelectricity in tetragonal ZrO thin films
Ali El Boutaybi, Thomas Maroutian, Ludovic Largeau +10
We report on the crystal structure and ferroelectric properties of epitaxial ZrO films ranging from 7 to 42 nm thickness grown on LaSrMnO-buffered (110)-o…
Electro-optic properties of ZrO2, HfO2 and LiNbO3 ferroelectric phases: A comprehensive and comparative study with density functional theory
Ali El Boutaybi, Panagiotis Karamanis, Thomas Maroutian +4
We report the Pockels electro-optic properties of ZrO2 and HfO2 orthorhombic Pbc21 and rhombohedral R3m ferroelectric phases, and we compare them to the well-known LiNbO3 Pockels m…
Bond orbital description of the strain induced second order optical susceptibility in silicon
Pedro Damas, Delphine Marris-Morini, Eric Cassan +1
We develop a theoretical model, relying on the well established sp3 bond-orbital theory, to describe the strain-induced in tetrahedrally coordinated centrosymmetric coval…
Electroabsorption study of index-defined semiconducting carbon nanotubes
Nicolas Izard, Etienne Gaufrès, Xavier Le Roux +6
Electroabsorption spectroscopy of well-identified index-defined semiconducting carbon nanotubes is reported. The measurement of high definition electroabsorption spectra allows dir…
Optical microcavity with semiconducting single-wall carbon nanotubes
Etienne Gaufrès, Nicolas Izard, Xavier Le Roux +4
We report studies of optical Fabry-Perot microcavities based on semiconducting single-wall carbon nanotubes with a quality factor of 160. We experimentally demonstrate a huge photo…
Enhancement of semiconducting single-wall carbon nanotubes photoluminescence
Etienne Gaufrès, Nicolas Izard, Laurent Vivien +3
Photoluminescence properties of semiconducting single wall carbon nanotubes (s-SWNT) thin films with different metallic single wall carbon nanotubes (m-SWNT) concentrations are rep…
