Imaging the nanoscale phase separation in vanadium dioxide thin films at terahertz frequencies
The insulator-to-metal transition in vanadium dioxide still has many unexplored properties. Here the authors use multi-modal THz and mid-IR nano-imaging to examine the phase transition in VO2 thin films, and discuss the unexpectedly smooth transition at THz frequencies in the context of a dimer Hubb...

| Sumario: | The insulator-to-metal transition in vanadium dioxide still has many unexplored properties. Here the authors use multi-modal THz and mid-IR nano-imaging to examine the phase transition in VO2 thin films, and discuss the unexpectedly smooth transition at THz frequencies in the context of a dimer Hubbard model. |
