摘要:

我们报告的微波诱导电阻振荡的观察与分数比n/m的微波辐射频率的回旋频率的m高达8在一个二维的电子系统与高电子密度。这些特征在高微波频率下猝灭,与分数阶m无关。我们分析了温度,功率和频率的磁阻振荡的依赖关系,并讨论它们与现有的理论。

英文摘要:

We report on the observation of microwave-induced resistance oscillations associated with the fractional ratio n/m of the microwave irradiation frequency to the cyclotron frequency for m up to 8 in a two-dimensional electron system with high electron density. The features are quenched at high microwave frequencies independent of the fractional order m. We analyze temperature, power, and frequency dependencies of the magnetoresistance oscillations and discuss them in connection with existing theories.
