Do you know about of thickness of the layer deposited?

In any case, why don't measure the roughness by AFM?

Diana Raie

I haven't AFM. No, I haven't thickness.

Well. I am not sure that it is possible to calculate the roughness if you don't know about type of growth of the film: planar, three-dimensional (islands), etc.
