Asmae Bouziani

you can use XPS or Raman spectroscpy.

Krishnan Raja

A simple way of quantification is to carry out Mott-Schottky analysis using electrochemical impedance spectroscopy and determine charge carrier density. However, here the assumption is that oxygen vacancies are the charge carriers. The assumption can be supported by XPS, Raman, or EPR (paramagnetic resonance) results.
