## Description

- description: The intermediate-range order of the covalently bonded glasses has been
    extensively discussed in terms of their diffraction peaks observed at low scattering
    angles called the first sharp diffraction peak (FSDP). Although atomic density
    fluctuations at the scale arising from the quasilattice planes are a critical
    scientific target, their direct experimental observation is still lacking. Here,
    we report the direct observation of atomic density fluctuations in silica glass
    by energy-filtered angstrom-beam electron diffraction. The correspondence between
    the local electron diffraction patterns of FSDPs and the atomic configurations
    constructed from X-ray and neutron diffraction reveals that the local atomic density
    fluctuations arise from the quasi-periodic alternating arrangements of columnar
    chain-like atomic configurations and interstitial tubular voids, as in crystals.
    We also discovered the longer-range fluctuations associated with the shoulder
    of the FSDP observed at the low Q side. The hierarchical fluctuations inherent
    in materials are helpful in elucidating their properties and performance.
