Paper Details

Diffusion of oxygen in YBa2Cu3O7 doped with silver was measured. It was seen that the diffusion of oxygen was slowed down by silver doping, as shown in the data here.
Temperature T (?C) Diffusion Coefficient D (cm2/s)
650..........................................................2.89 × 10-7
700..........................................................8.03 × 10-7
750..........................................................3.07 × 10-6
Assume that these data are sufficient to make a straight line fit for the relationship between ln(D) and 1/T and calculate the values of the activation energy for diffusion of oxygen in YBa2Cu3O7 containing silver.
