Webb30 juli 2010 · The study of the dielectric, piezoelectric and elastic properties of KH 2 PO 4 has been extended into the ferroelectric range of temperatures, and should permit further theoretical consideration of the behaviour of this group of crystals. WebbThe results for both phases are compared with those obtained from similar studies of KH2PO4. Whilst it is shown that the crystal structures of RbH2PO4 and KH2PO4 (and the way they change through the transition) are closely similar, some small but important differences are revealed.

The crystal has anomalously high dielectric constant in the temperature range below TC, compared to the predicted Landau theory roll-off. Below certain temperature Tf (< TC), permittivity falls back onto its expected phenomenological behavior.

WebbPercolation theory. In statistical physics and mathematics, percolation theory describes the behavior of a network when nodes or links are added. This is a geometric type of phase transition, since at a critical fraction of addition the network of small, disconnected clusters merge into significantly larger connected, so-called spanning clusters. Webb1 nov. 2024 · It is observed that the β-to-α phase transition proceeds through two energetically distinct processes, which are identified here as the nucleation and growth of an intermediate γ phase with random skew linkages followed by a γ-to-α transition.
