Query: Structural and electronic properties of realistic two-dimensional
  amorphous topological insulators   We investigate the structure and electronic spectra properties of
two-dimensional amorphous bismuthene structures and show that these systems are
topological insulators. We employ realistic modeling of amorphous geometries
together with density functional theory for electronic structure calculations.
We investigate the system topological properties throughout the amorphization
process and find that the robustness of the topological phase is associated
with the spin-orbit coupling strength and size of the pristine topological gap.
Using recursive non-equilibrium Green's function, we study the electronic
transport properties of nanoribbons devices with lengths comparable to
experimentally synthesized materials. We find a $2e^2/h$ conductance plateau
within the topological gap and an onset of Anderson localization at the trivial
insulator phase.
