Persistence of superconductivity in niobium ultrathin films grown on R-Plane Sapphire
Cécile Delacour, Luc Ortega, Marc Faucher +4
We report on a combined structural and electronic analysis of niobium ultrathin films (from 2 to 10 nm) deposited in ultra-high vacuum on atomically flat R-plane sapphire wafers. A…
Epitaxial refractory-metal buer layers with a chemical gradient for adjustable lattice parameter and controlled chemical interface
Olivier Fruchart, Anthony Rousseau, Didier Schmaus +3
We have developed and characterized the structure and composition of nanometers-thick solid-solution epitaxial layers of (V,Nb) on sapphire (1120), displaying a continuous lateral…
Martensite structures and twinning in substrate-constrained epitaxial Ni-Mn-Ga films deposited by a magnetron co-sputtering process
Jérémy Tillier, Daniel Bourgault, Sébastien Pairis +3
In order to obtain Ni-Mn-Ga epitaxial films crystallized in martensite structures showing Magnetic-Induced Rearrangement (MIR) of martensite variants, a fine control of the composi…
Ni-Mn-Ga films in the austenite and the martensite structures at room temperature: Uniaxial texturation and epitaxial growth
Jérémy Tillier, Antinéa Einig, Daniel Bourgault +7
Ni-Mn-Ga films in the austenite and the martensite structures at room temperature have been obtained using the DC magnetron sputtering technique. Two elaboration processes were stu…
Tuning macro-twinned domain sizes and the b-variants content of the adaptive 14-modulated martensite in epitaxial Ni-Mn-Ga films by co-sputtering
Jérémy Tillier, Daniel Bourgault, Philippe Odier +5
In order to obtain modulated-martensite in our epitaxial Ni-Mn-Ga films, we have tuned the composition by using a co-sputtering process. Here we present how the composition affects…
Low temperature transition to a superconducting phase in boron-doped silicon films grown on (001)-oriented silicon wafers
C. Marcenat, J. Kacmarcik, R. Piquerel +11
We report on a detailed analysis of the superconducting properties of boron-doped silicon films grown along the 001 direction by Gas Immersion Laser Doping. The doping concentratio…
