Query: Enhanced Electronic Transport in Disordered Hyperuniform Two-Dimensional
  Amorphous Silica   Disordered hyperuniformity (DHU) is a recently proposed new state of matter,
which has been observed in a variety of classical and quantum many-body
systems. DHU systems are characterized by vanishing infinite-wavelength density
fluctuations and are endowed with unique novel physical properties. Here we
report the first discovery of disordered hyperuniformity in atomic-scale 2D
materials, i.e., amorphous silica composed of a single layer of atoms, based on
spectral-density analysis of high-resolution transmission electron microscope
images. Subsequent simulations suggest that the observed DHU is closely related
to the strong topological and geometrical constraints induced by the local
chemical order in the system. Moreover, we show via large-scale density
functional theory calculations that DHU leads to almost complete closure of the
electronic band gap compared to the crystalline counterpart, making the
material effectively a metal. This is in contrast to the conventional wisdom
that disorder generally diminishes electronic transport and is due to the
unique electron wave localization induced by the topological defects in the DHU
state.
