How can we determine conduction band and or valence band offset using XPS?

26 October 2015 1 5K Report

2 nm Al2O3 is deposited on top of bulk Si wafer. I'd like to characterize the conduction band and/or valence band offset between Al2O3 and Si using XPS data. How can we interpret the XPS data to determine it? Thanks.

Thanks much! It helps a lot.
