We examine and compare the diagonal magnetoresistance, R xx , and the photo-voltage induced by microwave (42 ≤ f < 300GHz) and terahertz (f ≥ 300GHz) photoexcitation in the high mobility quasi two-dimensional GaAs/AlGaAs system. The data demonstrate strong radiation-induced magneto-resistance oscillations in R xx to 360GHz. In addition, cyclotron resonance is observed in the photo-voltage to 725GHz. These results show that our high mobility GaAs/AlGaAs 2DES specimens remain photo-active in magnetotransport into the terahertz band.

Zero-Differential Resistance State of Two-Dimensional Electron Systems in Strong Magnetic Fields

et al. 2007

View full text Add to dashboard Cite

Zero differential resistance state is found in response to direct current applied to 2D electron systems at strong magnetic field and low temperatures. Transition to the state is accompanied by sharp dip of negative differential resistance, which occurs above threshold value I th of the direct current. The state depends significantly on the temperature and is not observable above several Kelvins. Additional analysis shows lack of the linear stability of the 2D electron systems at I > I th and inhomogeneous, non-stationary pattern of the electric current in the zero differential resistance state. We suggest that the dc bias induced redistribution of the 2D electrons in energy space is the dominant mechanism leading to the new electron state.

“…From the experimental standpoint, remarkable contributions are being published in a continuous basis. Among them we can highlight activated temperature dependence in the magnetoresisitivity (ρ xx ) response 3,4,5 , quenching of ρ xx response at high microwave (MW) intensities 2,6 , absolute negative conductivity (ANC) and breakdown of ZRS 2,5,6,7 , suppression of MIRO and ZRS by in-plane magnetic field 8,9 and the evidence that MIRO and ZRS are notably immune to the sense of circular polarization of MW radiation 10 . Very recently, an experimental achievement has joined the group of new contributions.…”

Magnetoresistivity modulated response in bichromatic microwave irradiated two dimensional electron systems

We analyze the effect of bichromatic microwave irradiation on the magnetoresistivity of a two dimensional electron system. We follow the model of microwave driven Larmor orbits in a regime where two different microwave lights with different frequencies are illuminating the sample (w 1 and w 2 ). Our calculated results demonstrate that now the electronic orbit centers are driven by the superposition of two harmonic oscillatory movements with the frequencies of the microwave sources. As a result the magnetoresisitivity response presents modulated pulses in the amplitude with a frequency of w 1 −w 2 2 , whereas the main response oscillates with w 1 +w 2 2 . PACS numbers:
