内容記述 |
We present an electron diffraction study of three sillenites, Bi_<12>SiO_<20>, Bi_<25>FeO_<39>, and Bi_<25>InO_<39> synthesized using the solid-state method. We explore a hypothesis, inspired by optical studies in the literature, that suggests that trivalent sillenites have additional disorder not present in the tetravalent compounds. Electron diffraction patterns of Bi_<25>FeO_<39> and Bi_<25>InO_<39> show streaks that confirm deviations from the ideal sillenite structure. Multi-slice simulations of electron-diffraction patterns are presented for different perturbations to the sillenite structure - partial substitution of the M site by Bi^<3+>, random and ordered oxygen-vacancies, and a frozen-phonon model. Although comparison of experimental data to simulations cannot be conclusive, we consider the streaks as evidence of short-range ordered oxygen-vacancies. |
