Dear All,
I noticed that the spring forces for the Li case described in my previous post, are comparable or bigger
than real forces on the images. So I tried to reduce the spring forces by reducing SPRING constant from
-5 to -2 eV/A^2. The first iterations showed that spring forces are smaller than ...

NEB calculation on the defect surface of Ceria (111)
Dear All,
I am calculating the migration energy of the oxygen/vacancy on CeO2 surface, when its near neighbors are alkali metals (for example K, Li). The problem I have is that although the Li doped surface of Ceria (111) is converging nicely it has a problem with NEB
convergence. From the ...
