Growth of CaMnO Ruddlesden-Popper structured thin films using Combinatorial Substrate Epitaxy
M. Lacotte, A. David, D. Pravarthana +6
The local epitaxial growth of pulsed laser deposited CaMnO films on polycrystalline spark plasma sintered SrTiO substrates was investigated to determine phase forma…
Processing of formic acid-containing ice by heavy and energetic cosmic ray analogues
A. Bergantini, S. Pilling, H. Rothard +2
Formic acid (HCOOH) has been extensively detected in space environments, including interstellar medium (gas and grains), comets and meteorites. Such environments are often subjecte…
Interatomic Coulombic Decay as a New Source of Low Energy Electrons in slow Ion-Dimer Collisions
W. Iskandar, J. Matsumoto, A. Leredde +9
We provide the experimental evidence that the single electron capture process in slow collisions between O ions and neon dimer targets leads to an unexpected production of l…
High In-content InGaN layers synthesized by plasma-assisted molecular-beam epitaxy: growth conditions, strain relaxation and In incorporation kinetics
S. Valdueza-Felip, E. Bellet-Amalric, A. Núñez-Cascajero +7
We report the interplay between In incorporation and strain relaxation kinetics in high-In-content InxGa1-xN (x = 0.3) layers grown by plasma-assisted molecular-beam epitaxy. For I…
Optical characterization of PZT thin films for waveguide applications
Julien Cardin, Dominique Leduc, Thomas Schneider +3
In order to develop an electro-optic waveguide, Pb(Zr, Ti)O3 ceramic ferroelectric thin films were elaborated by a modified sol-gel process on glass substrate. In the aim to study…
Theoretical investigation of the more suitable rare earth to achieve high gain in waveguide based on silica containing silicon nanograins doped with either Nd3+ or Er3+ ions
Alexandre Fafin, Julien Cardin, Christian Dufour +1
We present a comparative study of the gain achievement in a waveguide whose active layer is constituted by a silica matrix containing silicon nanograins acting as sensitizer of eit…
Comparison of UV and high-energy ion irradiation of methanol:ammonia ice
G. M. Munoz Caro, E. Dartois, P. Boduch +3
The main goal of this work is to compare the effects induced in ices of astrophysical relevance by high-energy ions, simulating cosmic rays, and by vacuum ultraviolet (UV) photons.…
Atomic site sensitive processes in low energy ion-dimer collisions
W. Iskandar, J. Matsumoto, A. Leredde +9
Electron capture processes for low energy Ar9+ ions colliding on Ar2 dimer targets are investigated, focusing attention on charge sharing as a function of molecule orientation and…
Radiolysis of Amino Acids by Heavy and Energetic Cosmic Ray Analogs in Simulated Space Environments: -Glycine Zwitterion Form
Williamary Portugal, Sergio Pilling, Philippe Boduch +2
In this work, we studied the stability of the glycine molecule in the crystalline zwitterion form, known as α-glycine (NHCHCOO) under action of heavy cosmic…
Two components for one resistivity in LaVO3/SrTiO3 heterostructures
Helene Rotella, Olivier Copie, Alain Pautrat +6
A series of 100 nm LaVO3 thin films have been synthesized on (001)-oriented SrTiO3 substrates using the pulsed laser deposition technique, and the effects of growth temperature are…
Structural analysis of strained LaVO thin films
H. Rotella, O. Copie, G. Mouillard-Steciuk +10
While structure refinement is routinely achieved for simple bulk materials, the accurate structural determination still poses challenges for thin films due on the one hand to the s…
Dynamical amplification of phase conjugation using a modulated optical feedback in a Nd:YVO_4 laser
Hervé Gilles, Sylvain Girard, Mathieu Laroche +1
We demonstrate an efficient dynamical amplification of phase conjugation in the gain medium of a diode-pumped Nd3+:YVO4 solid state laser via excitation of its relaxation oscillati…
Energy deposition by heavy ions: Additivity of kinetic and potential energy contributions in hillock formation on CaF2
Y. Y. Wang, C. Grygiel, C. Dufour +17
The formation of nano-hillocks on CaF2 crystal surfaces by individual ion impact has been studied using medium energy (3 and 5 MeV) highly charged ions (Xe19+ to Xe30+) as well as…
Modeling of the electromagnetic field and level populations in a waveguide amplifier: a multi-scale time problem
Alexandre Fafin, Julien Cardin, Christian Dufour +1
A new algorithm based on auxiliary differential equation and finite difference time domain method (ADE-FDTD method) is presented to model a waveguide whose active layer is constitu…
