Abstract

Read online

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.
