Abstract

Superprotonic conduction in the LiH ₂PO ₄ (LDP) system has been studied by means of impedance spectroscopy. A dielectric dispersion associated with room-temperature superionic conduction is manifested, as the temperature-dependent dielectric constant displays a broad peak shifting toward the high temperatures with increasing measuring frequency. In particular, our impedance spectroscopic analysis in distinct temperature ranges has revealed the evolution of the microscopic proton dynamics and inhomogeneous electric environments associated with the dynamics of the two distinct hydrogen-bond types in LDP.
