We report on the dispersive ionic conductivity in
x
(
), where the number of available positions for the
mobile ions is reduced by introducing immobile
ions. At high frequency the conductivity is power law
dependent with an exponent which increases as the number of
accessible neighboring sites decreases. This result is
quantitatively accounted for in terms of a one-parameter
statistical microscopic model. We provide experimental and
theoretical evidence for the importance of reduced dimensionality
resulting from the blocked pathways in slowing down the dynamics
of diffusing ions.
