Query: Mapping the effect of defect-induced strain disorder on the Dirac states
  of topological insulators   We provide a detailed microscopic characterization of the influence of
defects-induced disorder onto the Dirac spectrum of three dimensional
topological insulators. By spatially resolved Landau-levels spectroscopy
measurements, we reveal the existence of nanoscale fluctuations of both the
Dirac point energy as well as of the Dirac-fermions velocity which is found to
spatially change in opposite direction for electrons and holes, respectively.
These results evidence a scenario which goes beyond the existing picture based
on chemical potential fluctuations. The findings are consistently explained by
considering the microscopic effects of local stain introduced by defects, which
our model calculations show to effectively couple to topological states,
reshaping their Dirac-like dispersion over a large energy range. In particular,
our results indicate that the presence of microscopic spatially varying stain,
inevitably present in crystals because of the random distribution of defects,
effectively couple to topological states and should be carefully considered for
correctly describing the effects of disorder.
