Webb30 juli 2024 · Antiferroelectric configuration with specific antiparallel dipoles has been used to establish antiferroelectric theories and understand its characteristic behaviors. … Unexpectedly, our data suggest that there is no critical softening in the lattice except for the Γ relaxational mode. Therefore, the next objective becomes the understanding of the relationship between this critical process and other observed phenomena, namely, (1) the anomalous dispersion and non-critical softening of … Visa mer At high temperatures, PZ has the ideal cubic perovskite structure shown in Fig. 1a. After cooling through a first-order phase transition at TA~ 500 K, the structure changes … Visa mer For information on the lattice vibration softening in the high-temperature phase, we examined the Σ, Γ and R points of the Brillouin zone, using … Visa mer
