Consistent transition model for Bi0.5Na0.5TiO3 from temperature-dependent structural and electrical properties
Thomas Fourgassie, Omar Ibder, Cosme Milesi-Brault +5
BNT based solid solutions are promising parent materials for lead free dielectric capacitors, thanks to their high recoverable energy densities and breakdown strengths. However, th…

Phonon studies of the phase transition sequence in antiferroelectric single crystal of Pb(Hf0.83Sn0.17)O3
Anirudh K. R., Cosme Milesi-Brault, Christelle Kadlec +5
The sequence of phase transitions in PbHf0.83Sn0.17O3 has been studied by THz, far infrared and Raman spectroscopies, revealing the complementary behaviour of both, polar and non-p…

Band gap tuning by structural phase transition in Sm-substituted BiFeO3 powders
Christina Hill, Michele Melchiorre, Cosme Milesi-Brault +6
The substitution of bismuth by samarium in BiFeO3 is known to induce a structural phase transition from the polar phase to a non-polar phase, with a possible antiferroelectric inte…
