(a) Current, I, as a function of applied voltage, V, near the dynamic Mott MIT for a range of densities near fc, fc − f < 0.015. Red line represents the best fit of data in the form (4) for f = 0.499. Solid (empty) circles represent data points outside (inside) of the critical regime. (b) Current, I, as a function of deviation of applied voltage from the critical value, V − Vc, for Vc = 0.238. Red straight line fits data points in the critical regime with power-law scaling above the transition (for V > Vc).
