the resistivity of Pt deposited from Innotec

Accurately measuring the resistivity especially for thin film Pt is 
quite difficult because pt doesn't stick well to oxide. As a result, an 
adhesion layer such as Ti or W is needed. Both of these buffer layers 
form oxides and you will likely end up with a stack of Ti (or W), their 
native oxides, and then Pt. Extracting the resistivity contribution of 
just Pt will require very careful planning and calibration.
For my case, i had a 10nm layer of W and 20nm Pt and the measured 
resistivity (after anneal) was about 80uohm-cm which is about ~10X the 
bulk value of the combination (reference: wikipedia). If anyone has a 
reference to thin film resistivity data, it will be very helpful to the 
innotec community.
I hope this helps.
