What can be the reason for reduction in hardness and toughness of thin films or coatings due to doping with silver (Ag) ?

I have deposited pure Cr and W films by unbalanced magnetron sputtering method and then prepared films by doping them with Ag. The hardness and modulus of these coatings are lower than that of the...

Does the presence of excess lattice oxygen in thin films or coatings signify high surface energy of the films or coatings?

In cerium oxide coatings, I have found that there are excess lattice oxygen when oxygen to metal ratio is quite high. Does it mean that the coatings have higher surface energy when there is excess...
