metal-insulator transition

[′med·əl ¦in·sə‚lād·ər tran′zish·ən]
(solid-state physics)
The change of certain low-dimensional conductors from metals to insulators as the temperature is lowered through a certain value, due to the lattice distortion and band gap accompanying the onset of a charge-density wave.

The almost zero slopes with small fluctuations of W versus log T plots in the 78-230 K range indicate that the films grown in control, and EMITF solutions are on the metallic side of the metal-insulator transition with these two being closer to the critical regime (36).
The metal-insulator transition observed only for the PPy films obtain from conventional electrolyte above the transition regime, further, supports our findings that intrinsic differences between the physicochemical properties of ionic liquids and conventional liquid electrolytes ensue in films with altogether different properties.
