SUMMARY
The activation energy (Ea) of a PZT sample can be calculated using an Arrhenius plot of ln(conductivity) versus 1000/T. After determining the slope from this graph, the next step involves transforming the original equation ln(conductivity) = Aexp(-Ea/KT) into ln(ln(conductivity)) = -Ea/kT + lnA. By plotting ln(ln(conductivity)) against 1/T, the slope will yield -Ea/k, allowing for the calculation of Ea using Boltzmann's constant (k = 1.38 x 10^(-23)).
