Deposited Gold for Charge Referencing – Be Careful
The Au 4f7 BE from 1-6 nm films of sputter deposited Gold are reported to change:
- as the thickness of the Gold increases, and
- as a function of time because small clusters move to form large clusters
These two issues make it very difficult to use thin films of sputter deposited Gold for Charge Referencing.
