Millimeter wave radiation-induced magnetoresistance oscillations in the high quality GaAs/AlGaAs 2D electron system under bichromatic excitation. Phys. Rev. B 95, 1953042469-9950https://hdl.handle.net/10016/31764Millimeter wave radiation-induced magnetoresistance oscillations are examined in the GaAs/AlGaAs 2D electron system under bichromatic excitation in order to study the evolution of the oscillatory diagonal magnetoresistance, R-xx as the millimeter wave intensity is changed systematically for various frequency combinations. The results indicate that at low magnetic fields, the lower frequency millimeter wave excitation sets the observed R-xx response, as the higher frequency millimeter wave component determines the R-xx response at higher magnetic fields. The observations are qualitatively explained in terms of the order of the involved transitions. The results are also modeled using the radiation-driven electron orbit theory.eng© 2017 American Physical SocietyZero-resistance statesMicrowave-radiationHeterostructuresPhotoexcitationDevicesDrivenGasresearch articleFísicahttps://doi.org/10.1103/PhysRevB.95.195304open access19Physical Review B95AR/0000020022
