Influence of Temperature, Pressure and Humidity on the Stabilities and Transitions Kinetics of the Various Polymorphs of FAPbI
Francesco Cordero, Floriana Craciun, Francesco Trequattrini +4
The phase transitions between the various polymorphs of FAPbI (FAPI, FA = formamidinium CH(NH)) are studied by anelastic, dielectric and X--ray diffraction meas…
Stability of Cubic FAPbI from X-ray Diffraction, Anelastic, and Dielectric Measurements
Francesco Cordero, Floriana Craciun, Francesco Trequattrini +4
Among the hybrid metal-organic perovskites for photovoltaic applications FAPbI_3 (FAPI) has the best performance regarding efficiency and the worst regarding stability, even though…
Competition between Polar and Antiferrodistortive Modes and Correlated Dynamics of the Methylammonium Molecules in MAPbI from Anelastic and Dielectric Measurements
Francesco Cordero, Floriana Craciun, Francesco Trequattrini +3
The mechanisms behind the exceptional photovoltaic properties of the metallorganic perovskites are still debated, and include a ferroelectric (FE) state from the ordering of the el…
Elastic aging from coexistence and transformations of ferroelectric and antiferroelectric states in PZT
Francesco Cordero, Floriana Craciun, Francesco Trequattrini +2
Materials undergoing antiferroelectric/ferroelectric (AFE/FE) transitions are studied for possible applications that exploit the large volume, charge and entropy differences betwee…
Effects of coupling between octahedral tilting and polar modes on the phase diagram of PbZr1-xTixO3 (PZT)
F. Cordero, F. Trequattrini, F. Craciun +1
The results are presented of anelastic and dielectric spectroscopy measurements on large grain ceramic PZT with compositions near the two morphotropic phase boundaries (MPBs) that…
Mechanical and Dielectric Response of PZT and Tetragonal to Monoclinic Phase Transition: I. Theory
O. Hudak, F. Cordero, F. Craciun
The PZT material near the morphotropic phase boundary where a monoclinic phase was observed is studied. A theory of the tetragonal to monoclinic phase transition was developed with…
Polar and non-polar atomic motions in the relaxor ferroelectric PLZT from dielectric, anelastic and NMR relaxation
F. Cordero, M. Corti, F. Craciun +3
Dielectric, anelastic and ^139La NMR relaxation measurements have been made on the relaxor ferroelectric Pb(1-3x/2)La(x)Zr(0.2)Ti(0.8)O(3) (PLZT) with x = 0.22. The dielectric susc…
