The O/Hf relative concentration of the as-deposited thin films reveals almost stoichiometry (1.96:1). The deconvolution of Hf 4f peak at 16.2 eV and 17.9 eV indicate the formation of 4f 7/2 and 4f 5/2 corresponding to Hf 4f in hafnium oxide as-deposited films. The spectrum also suggests a small visible sub-peak towards the lower binding energy.
