Abstract

We report experimental results on charge transport in a low-disorder and low-density one-dimensional electron system. At zero magnetic field (B=0), we observe quantized conductance steps in our sample, which is a channel longer than 1.2 μm. At B0, we observe the integer and the fractional quantum Hall effect. In the extremely high-B limit, we find a gate tunable transition from the fractional quantum Hall effect to an insulating phase and observe conductance oscillations as a function of density in this B-induced insulating phase. A careful study of the temperature dependence and the current-voltage characteristics of these conductance oscillations is made and the results are consistent with the recent theoretical model of a one-dimensional Wigner solid.
