Abstract
The diffusion process of silver ions in α-Te is investigated. It is assumed that Ag ions occupy the tetrahedral sites and octahedral sites with different probability. To give an explanation of the Havens ratio obtained by a molecular-dynamics calculation, a theory of caterpillar mechanism proposed by Yokota [J. Phys. Soc. Jpn. 21, 420 (1966)] is used. It is shown that the ratio of the frequency of a single jump to that of cooperative jumps increases with increasing temperature.
