摘要:

我们报告的状态,其特征在于在非常高的朗道能级的高迁移率的二维电子系统中观察到的零微分电阻。从最小的霍尔场引起的电阻振荡在低温下出现,这种状态存在于一个连续的范围内的磁场延伸远低于舒布尼科夫-德哈斯效应的发病。支持这种状态所需的最小电流在很大程度上与磁场无关,而最大电流随着磁场跟踪朗道能级间散射的开始而增加。

英文摘要:

We report on a state characterized by a zero differential resistance observed in very high Landau levels of a high-mobility two-dimensional electron system. Emerging from a minimum of Hall field-induced resistance oscillations at low temperatures, this state exists over a continuous range of magnetic fields extending well below the onset of the Shubnikov-de Haas effect. The minimum current required to support this state is largely independent on the magnetic field, while the maximum current increases with the magnetic field tracing the onset of inter-Landau level scattering.
