Deposited rates

This is done by a sputtering process. Process parameters (argon pressure and effect) can be varied, the surface roughness and the deposition rate (see here) and may change with these settings.


Deposited film characteristics

AFM pictures show how the surface roughness is dependent of the process parameters, this can be seen here.
