本文研究了微波辐射对一维横向超晶格中二维电子低温磁输运的影响。这种超晶格是基于选择性掺杂的GaAsAlAs异质结。结果表明，在微波辐射作用下，这种超晶格中二维电子气的电阻在公度振荡的极小值处比在极大值处变化得更大。实验数据证明了经典公度磁阻振荡和量子微波诱导振荡的“干涉”。
The influence of microwave radiation on the low-temperature magnetotransport of two-dimensional electrons in a one-dimensional lateral superlattice fabricated on the basis of a selectively doped GaAs/AlAs heterojunction has been investigated. It has been found that the resistance of the two-dimensional electron gas in this superlattice changes under the action of microwave radiation more substantially at the minima of commensurate oscillations than at the maxima. The experimental data demonstrate “interference” of classical commensurate magnetoresistance oscillations and quantum microwave-induced oscillations.
