      abstract     = {The current market launch of HfO$_ 2$ -based ferroelectric
                      devices relies on the control of the inherent oxygen
                      vacancies (OVs) and their impact on the ferroelectric
                      performance. Due to the necessary stabilization of the
                      ferroelectric phase by doping, several dopants are
                      investigated for their applicability to control the vacancy
                      concentration. Hf mathematical equation signatures in X-ray
                      photoemission spectra are often used as an indication of OVs
                      for both qualitative and quantitative analysis. The analysis
                      of Y doped HfO$_ 2$ (Y:HfO$_ 2$) as investigated by hard
                      x-ray photoelectron spectroscopy (HAXPES) reveals the
                      inapplicability of the Hf mathematical equation signature
                      for a quantitative determination of OVs in the case of
                      heterovalent doping and is restricted to pure HfO$_ 2$ or
                      isoelectronic substitution of Hf by, for example, Zr.},
