Using the extensively studied V2O3 as a prototype system, we investigate therole of percolation in metal-insulator transition (MIT). We apply scanningmicrowave impedance microscopy to directly determine the metallic phasefraction p and relate it to the macroscopic conductance G, which shows a suddenjump when p reaches the percolation threshold. Interestingly, the conductance Gexhibits a hysteretic behavior against p, suggesting two different percolatingprocesses upon cooling and warming. Based on our image analysis and modelsimulation, we ascribe such hysteretic behavior to different domain nucleationand growth processes between cooling and warming, which is likely caused by thedecoupled structural and electronic transitions in V2O3 during MIT. Our workprovides a microscopic view of how the interplay of structural and electronicdegrees of freedom affects MIT in strongly correlated systems.
