Dense and single-phase KTaO ceramics obtained by spark plasma sintering
L. Féger, F. Giovannelli, G. Vats +5
Potassium tantalate (KTaO) is a promising material for dielectric applications at low temperature. However, dense and single-phase ceramics cannot be obtained by conventional…
Influence of cation vacancy concentrations on ultra-low thermal conductivity in BiVO-BiMoO scheelite solid solutions
Guillaume F. Nataf, Hicham Ait Laasri, Damien Brault +5
Bismuth vanadate - bismuth molybdate solid-solution was prepared to elaborate ceramics with different amounts of cation vacancies. Dense ceramics with similar microstructures were…
Ultra-low lattice thermal conductivity in tungsten-based scheelite ceramics
Hicham Ait Laasri, Eliane Bsaibess, Fabian Delorme +2
, and polycrystalline ceramics were synthesized by conventional solid-state reaction route. The effect of cati…
Influence of generated defects by Ar-implantation on the thermoelectric properties of ScN
R. Burcea, J. -F. Barbot, P. -O. Renault +9
Nowadays, making thermoelectric materials more efficient in energy conversion is still a challenge. In this work, to reduce the thermal conductivity and thus improve the overall th…
P-type behavior of CrN thin films by control of point defects
Arnaud le Febvrier, Davide Gambino, Fabien Giovannelli +5
We report the results of a combined experimental and theoretical study on nonstoichiometric CrN1+d thin films grown by reactive magnetron sputtering on c-plane sapphire, MgO (100)…
Characterization of the Intra-Unit-Cell magnetic order in Bi2Sr2CaCu2O8+d
L. Mangin-Thro, S. De Almeida-Didry, Y. Sidis +3
As in YBa2Cu3O6+x and HgBa2CuO8+d, the pseudo-gap state in Bi2Sr2CaCu2O8+d is characterized by the existence of an intra-unit-cell magnetic order revealed by polarized neutron scat…
Evidence for Intra-Unit-Cell magnetic order in Bi2Sr2CaCu2O8+d
S. De Almeida-Didry, Y. Sidis, V. Baledent +3
Polarized elastic neutron scattering measurements have been performed in the bilayer copper oxide system Bi2Sr2CaCu2O8+d, providing evidence for an intra unit cell (IUC) magnetic o…
Non-linear electronic transport and anomalous resistance fluctuations in the stripes state of
A. Pautrat, F. Giovannelli, N. Poirot
We report on electronic transport measurements in . Non-Ohmic and hysteretic curves are measured for 220 . Large and non Gaussian resistance…
