title = "Conductivity measurement of genetically annealed zirconia from molecular dynamics simulations",
abstract = "Characteristics of the annealed state of yttria and scandia stabilized zirconia have been investigated using molecular dynamics simulations. A genetic algorithm was used to find the minimal energy configuration of dopant ions to simulate the effects of annealing for compositions of 8 mol\% Y2O 3 in ZrO2, and compositions with 9, 10 and 11 mol\% Sc 2O3 with, respectively, 2, 1 and 0 mol\% Y 2O3 in ZrO2. Conductivity and diffusion coefficients were calculated in each case, and it was discovered that the conductivity increased when the dopant ions were located distant to each other, and the number of first neighbor dopant-dopant pairs were reduced. Furthermore, the Haven ratio was calculated to be on the order of 0.9 for the 11 mol\% doped specimens, but substantially lower for the 8 mol\% yttria in zirconia specimens.",
