TL;DR: In this article, the influence of the polarization of the incident radiation on the recently discovered microwave-induced resistance oscillations in state-of-the-art 2D electron systems was investigated.
Journal ArticleDOI
Ultraslow electron spin dynamics in the fractional quantum Hall regime
TL;DR: In this article, the spin-reversed charged excitations of the Hall ground state are localized over the NMR time scale of ∼40 μs, by varying NMR pulse parameters, the electron spin temperature could be driven above the lattice temperature.
Proceedings ArticleDOI
Crossover from diffusive to ballistic transport as a function of frequency in a two dimensional electron gas
TL;DR: In this paper, the crossover from diffusive to ballistic transport as a function of frequency in dc contacted 2DEG was studied and it was shown that in the diffusive limit there are many scattering events between electric field cycles.
Proceedings ArticleDOI
Ultrafast spectral interferometry of resonant secondary emission from quantum wells: From Rayleigh scattering to coherent emission from biexcitons
TL;DR: In this article, it was shown that it is possible to isolate and time resolve the coherent field associated with the Rayleigh component using ultrafast spectral interferometry or Tadpole, thus, obtaining substantial and new information of the nature of resonant secondary emission.
