How can I determine the Mott Schottky effect for a semiconducting film (200 nm) deposited on a highly doped (0.05 ohms) n type Si substrate?

I would like to know if it is possible to determine the sign of carriers and concentration (from 1/C2 vs Bias dependency) for such system. It is crucial to deposit the film on a metallic...
