Abstract

We calculated the optical constants of the monoclinic phase of a Hf O 2 film from reflection spectra measured using synchrotron radiation in the spectral region from 143 eV to 927 eV , which includes the Hf N 4 , 5 , Hf N 2 , 3 , and OK absorption edges. The calculations were carried out using the Kramers– Kronig relations. It could be shown that the relation R ( E ) E 4 can be used for extrapolation of the experimental reflection spectrum of Hf O 2 (and probably of other heavy elements) for energies such that θ / θ c > 3.7 .
