Dephasing and the metal-insulator transition
The metal-insulator transition (MIT) observed in two-dimensional (2D) systems is apparently contradictory to the well-known scaling theory of localization. By investigating the conductance of disordered one-dimensional systems with a finite phase coherence length, we show that by changing the phase-coherence length or the localization length, it is possible to observe …
