"ferroelectric phase... higher number oxygen vacancies... X-ray photoelectron spectroscopy... calculate oxygen vacancy concentrations... undercount oxygen vacancies... one parameters stabilize ferroelectric phase... overturns conventional wisdom suggested size of crystal stabilizes hafnium oxide... three samples with equal grain sizes and different oxygen vacancy concentrations.... phases present varied... oxygen vacancy concentration more important than grain size"
