Description
There is an uncertainty surrounding the generation of defects associated with superionic conductivity in terms of whether these are created at an observed transitional temperature Tc, or at an earlier temperature point. The measured conductivity becomes more pronounced at a temperature coinciding with the deviation of constant lattice parameter from 6.2096 angstrom. The Frenkel pairs responsible for superionic region are generated well below the actual transitional temperature and this is informed by the calculation of S-parameter and positron lifetime.
