Classical versus quantum effects in the B=0 conducting phase in two dimensions

Year: 1999

Type: article

Abstract: In a dilute two-dimensional electron system in silicon, we show that the temperature below which Shubnikov--de Haas oscillations become apparent is approximately the same as the temperature below which an exponential decrease in resistance is seen in $B=0,$ suggesting that the anomalous behavior in zero field is observed only when the system is in a degenerate (quantum) state. The temperature dependence of the resistance is found to be qualitatively similar in $B=0$ and at integer Landau-level filling factors.
