“…Further, the analysis by showed that heating of the 2DEG leads to additional ω π /ω c -oscillations with a phase shift with respect to the equilibrium PIRO. Separately, nonlinear mixing of PIRO and MISO in two-subband systems was shown by Bykov et al (2010a); to lead to oscillations at frequencies determined by ω π and the subband splitting energy. A further example of frequency mixing for the case of MIRO and HIRO is discussed in Sec.…”

“…Oscillations similar to MISO occur also in a double QW with the lowest subband states split by tunneling or, for that matter, in any other system whose energy spectrum exhibits two or more series of LLs, which are offset with respect to each other, in the presence of scattering between the series. Experimentally, MISO were studied in two-subband single QWs (Bykov et al, 2010a;Coleridge, 1990;Leadley et al, 1992Leadley et al, , 1989Rowe et al, 2001;Sander et al, 1998), in double (Bykov, 2008b;Mamani et al, 2008) and triple (Wiedmann et al, 2009b) QWs, and in wide QWs split in two layers electrostatically (Wiedmann et al, 2010a). MISO were also studied theoretically in 2D layers with electron states split by spin-orbit interaction (Langenbuch et al, 2004).…”

“…Interplay of PIRO and MISO was investigated by Bykov et al (2010a) in a single GaAs QW with two populated subbands. Recent studies (Zhang et al, 2008b) of PIRO in a strong Hall field established that the dc field leads to the evolution of the PIRO maxima into minima and back, see Fig.…”

Developments in the physics of 2D electron systems during the last decade revealed a new class of nonequilibrium phenomena in the presence of a moderately strong magnetic field. The hallmark of these phenomena is magnetoresistance oscillations generated by the external forces that drive the electron system out of equilibrium. The rich set of dramatic phenomena of this kind, discovered in high mobility semiconductor nanostructures, includes, in particular, microwave radiation-induced resistance oscillations and zero-resistance states, as well as Hall field-induced resistance oscillations and associated zero-differential resistance states. The experimental manifestations of these phenomena and the unified theoretical framework for describing them in terms of a quantum kinetic equation are reviewed. This survey also contains a thorough discussion of the magnetotransport properties of 2D electrons in the linear-response regime, as well as an outlook on future directions, including related nonequilibrium phenomena in other 2D electron systems.

“…Such a behavior is similar to the motion of quantized vortices in superfluids, for example in the nucleation of vortices at a plane boundary [8,9], with the Magnus force (analog of the Lorentz force on an electron) balancing the external force [10]. The Zener tunneling processes in the quantum Hall regime of a 2-DEG are central in the quasi-elastic inter-Landau level scattering (QUILLS) [11,12] and in the magnetoresistance oscillations in the ohmic regime [13,14]. The gyrotropic theory, however, is distinct from them in its implications for the IV-characteristics.…”

We have investigated the cross-over from Zener tunneling of single charge carriers to avalanche type of bunched electron transport in a suspended graphene Corbino disk in the zeroth Landau level. At low bias, we find a tunneling current that follows the gyrotropic Zener tunneling behavior. At larger bias, we find avalanche type of transport that sets in at a smaller current the larger the magnetic field is. The low-frequency noise indicates strong bunching of the electrons in the avalanches. On the basis of the measured low-frequency switching noise power, we deduce the characteristic switching rates of the avalanche sequence. The simultaneous microwave shot noise measurement also reveals intrinsic correlations within the avalanche pulses and indicate decrease of correlations with increasing bias.

“…Later, the Zener oscillations of the magnetoresistance r xx were found in highly doped GaAs quantum wells 2 , in double quantum wells 3 and in hole gas 4 . Very recently the Zener oscillations are detected in the differential conductance of Corbino discs, where the Hall electric field E H is absent 5 .…”
