MECHANISM OF SUPERPROTONIC CONDUCTIVITY IN CSHSO4

Cesium hydrogen sulphate is one of the most extensively studied superp rotonic conductors with hydrogen bonds. The first-order phase transiti on, from the low-conductivity to high conductivity phase takes place a t 414 K. The crystallographic structure of both phases has been establ ished using high-resolution powder diffraction. Quasi-elastic neutron scattering gave information about the spatial and temporal characteris tics of proton transport. The present paper reports the results of rev erse Monte Carlo modelling of diffraction data which makes it possible to obtain the diffusion pathways for protons. (C) 1998 Elsevier Scien ce B.V.
