Abstract

The high temperature phase in Tl H2 P O4, a hydrogen-bonded antiferroelectric/ferroelastic material, was investigated by ac impedance measurements. A Warburg diffusion was manifested in the low-frequency region in the Cole-Cole plots near the ferroelastic transition temperature Tc′ =357 K, indicating a surface instability. The temperature dependent impedance, analyzed by a simple equivalent circuit model, was discussed in view of hydrogen delocalization on the surface.
