Query: Real-space observation of emergent complexity of phase evolution in
  micrometer-sized IrTe$_2$ crystals   We report complex behaviors in the phase evolution of transition-metal
dichalcogenide IrTe$_2$ thin flakes, captured with real-space observations
using scanning Raman microscopy. The phase transition progresses via growth of
a small number of domains, which is unlikely in statistical models that assume
a macroscopic number of nucleation events. Consequently, the degree of phase
evolution in the thin flakes is quite variable for the selected specimen and
for a repeated measurement sequence, representing the emergence of complexity
in the phase evolution. In the $\sim$20-$\mu$m$^3$-volume specimen, the complex
phase evolution results in the emergent coexistence of a superconducting phase
that originally requires chemical doping to become thermodynamically stable.
These findings indicate that the complexity involved in phase evolution
considerably affects the physical properties of a small-sized specimen.
