Query: Observation and manipulation of a phase separated state in a charge
  density wave material   The 1T polytype of TaS$_\textrm{2}$ has been studied extensively as a
strongly correlated system. As 1T-TaS$_\textrm{2}$ is thinned towards the 2D
limit, its phase diagram shows significant deviations from that of the bulk
material. Optoelectronic maps of ultrathin 1T-TaS$_\textrm{2}$ have indicated
the presence of non-equilibrium charge density wave phases within the
hysteresis region of the nearly commensurate (NC) to commensurate (C)
transition. We perform scanning tunneling microscopy on exfoliated ultrathin
flakes of 1T-TaS$_\textrm{2}$ within the NC-C hysteresis window, finding
evidence that the observed non-equilibrium phases consist of intertwined,
irregularly shaped NC-like and C-like domains. After applying lateral
electrical signals to the sample we image changes in the geometric arrangement
of the different regions. We use a phase separation model to explore the
relationship between electronic inhomogeneity present in ultrathin
1T-TaS$_\textrm{2}$ and its bulk resistivity. These results demonstrate the
role of phase competition morphologies in determining the properties of 2D
materials.
