Charging of oxide films under x rays is an important issue that must be taken into consideration for determination of core-level binding energies as well as valence band offsets. Measurements are taken as a function of time, thickness, and annealing condition. Photoemission results show the presence of metallic Hf with the 4f7/2 binding energy of 18.16 eV, and at least one clear suboxide peak.
