Abstract
Measurements of thermoelectric power have been performed below a superionic transition on Rb3H(SeO4)(2). The thermoelectric power S indicated the posi tive sign above about 350 K. This fact indicates that the majority carriers are protons. From this result, it was found that the electrical conduction below the superionic transition (T-c = 449 K) is caused by protons. Moreov er, from the temperature dependence of S, the activation energy for proton motion below T-c is determined to be 0.45 eV. (C) 2001 Elsevier Science Ltd . All rights reserved.
