“…The excess noise prior to the breakdown of the QHE behaves in a way closely related to the prebreakdown of the QHE. 21,33,44 Figure 7(a) shows G(V sd ) and S(V sd ) as a function of the normalized source-drain bias voltage (V sd /V BD ) obtained around the ν = 2 QHE state. Data obtained at B = 4.2, 4.0, and 3.8 T are plotted as circles, triangles, and squares, respectively.…”

“…The excess noise may provide us with direct information on the effective electron temperature, which can be compared to the values calculated from the longitudinal resistance. 33,34 To the best of our knowledge, there has been no experimental work that has studied these aspects.…”

“…Second, unexpectedly, we observed finite excess noise prior to the QHE breakdown at a finite V sd that is smaller than the onset voltage of the QHE breakdown (a V sd region that we define as a precursor regime), indicating the presence of finite dissipation in the nonequilibrium QHE states. The excess noise behaves in a way closely related to the prebreakdown of the QHE 21,33,44 . Thus, the noise measurement may give us profound information about onset of the breakdown of the QHE.…”

We performed noise measurements in a two-dimensional electron gas to investigate the nonequilibrium quantum Hall effect (QHE) state. While excess noise is perfectly suppressed around the zero-biased QHE state reflecting the dissipationless electron transport of the QHE state, considerable finite excess noise is observed in the breakdown regime of the QHE. The noise temperature deduced from the excess noise is found to be of the same order as the energy gap between the highest occupied Landau level and the lowest empty one. Moreover, unexpected finite excess noise is observed at a finite source-drain bias voltage smaller than the onset voltage of the QHE breakdown, which indicates finite dissipation in the QHE state and may be related to the prebreakdown of the QHE.

“…A model for thermal runaway [25] was proposed for the hysteretic I-V characteristics observed for the integer quantum Hall states [26]. We first consider the possibility of self-heating below threshold, i.e., on the branch of the I-V characteristic that carries virtually no current.…”

We report an unusual breakdown of the magnetically induced Wigner solid in an exceptional two-dimensional electron gas. The current-voltage characteristic is found to be hysteretic in the voltage biased setup and has a region of negative differential resistance in the current biased setup. When the sample is current biased in the region of negative differential resistance, the voltage on and the current through the sample develop spontaneous narrow band oscillations.

“…Many explanations have been proposed [10][11][12][13][14][15][16][17] for the complicated nonlinear breakdown phenomenona. In order to avoid controversy about which explanation is appropriate, we use a simple model [6] then IVx =r(2/i)MA(0c, where r is the total transition rate and i is the Hall plateau number.…”

Quantized breakdown voltage states are observed in a second, wide, highquality GaAs/AlGaAs sample made from another wafer, demonstrating that quantization of the longitudinal voltage drop along the sample is a general feature of the quantum Hall effect in the breakdown regime. The voltage states are interpreted in a simple energy conservation model as occurring when electrons are excited to higher Landau levels and then return to the original level. A spectroscopic study of these dissipative voltage states reveals how well they are quantized. The statistical variations of the quantized voltages increase linearly with quantum number.
