Abstract
We describe a model for static and dynamic behavior of KH2PO4 (KDP) type crystals in the ferroelectric phase, and for proton glass crystals of this type in the temperature and composition range in which the ferroelectric and paraelectric phases coexist. Model predictions are compared with experimental results for ferroelectric RbH2AsO4 (RDA) and for the proton glass Rb1−x(NH4)xH2AsO4 (RADA). The model is based on the statistical mechanics and dynamics of a fundamental excitation in the ferroelectric phase, namely chains consisting of nonpolar H2AsO4 groups with an H3AsO4 group at one end and an HAsO4 group at the other end.
