论文摘要
我们证明，在固态二维电子系统中，微波诱导的电阻振荡（MIRO）对圆极化感的长期免疫力并不是这种现象的通用特性。使用大区域GAAS的异质结构，我们检测到较大的Miro Signal，可用于转基因共振（CR）主动螺旋性，完全与同时测量的透射率和Drude吸收的CR形状完全一致。我们进一步详细阐述条件，以避免外部因素能够产生光增强剂的明显免疫力。
We demonstrate that long-debated immunity of microwave-induced resistance oscillations (MIRO) to the sense of circular polarization is not a generic property of this phenomenon in solid-state two-dimensional electron systems. Using a large-area GaAs-based heterostructure we detect up to 30 times larger MIRO signal for the cyclotron resonance (CR) active helicity, fully consistent with the concurrently measured transmission and the deduced CR shape of the Drude absorption. We further elaborate conditions to avoid extrinsic factors capable of producing an apparent immunity of the photoresponse.
