## Description

- description: "The amorphous phase of bismuth silicate (Bi2SiO5) is characterized
    by an exceptionally large\r\ndielectric permittivity over a wide temperature range.
    This study explores the relationship between\r\nthis remarkable property and the
    material’s atomic-scale structure, which has been modeled from\r\nexperimental
    X-ray and neutron scattering as well as EXAFS and NMR spectroscopy data in a\r\nReverse
    Monte-Carlo approach. The resulting structural model is analyzed to reveal short-
    and\r\nintermediate-range features on the atomic scale.\r\n  Our results show
    that the exceptional dielectric performance stems from the asymmetric coor-\r\ndination
    of Bi-Ox polyhedra as well as a nano-segregation induced by SiO4 chains, which
    together\r\nboost local polarizability. These findings establish a direct link
    between disordered atomic struc-\r\ntures and enhanced dielectric properties,
    and sets a new benchmark for amorphous materials."
