Abstract:

The proton conduction mechanism in M3H(XO4)2 crystals has been employed as an example for demonstrating, how such a mechanism can be broken up into a number of different types of proton motion starting with internal and lattice vibrations at short times of the order of 10–13 s and ultimately leading to H+-diffusion on the 10–9 s to 10–8 s time-scale as required for proton conductivity.
