    Evidence for a fractionally quantized Hall state with anisotropic longitudinal transport

    In strong magnetic fields, clean two-dimensional electron systems support fractional Hall states that exhibit isotropically vanishing longitudinal resistance. At low field these states disappear and an anisotr...

    Anisotropic state of two-dimensional electron gas in high Landau levels

    When several Landau levels of a high mobility two-dimensional electron system are occupied, transport measurements reveal evidence for intriguing new phenomena at low temperature. Near half filling in the N=2 and...

    Evidence for Virtual Phonon Exchange Between 2-D Electron Gases

    This paper reviews our study of the interaction of phonons with two-dimensional electron gases (2DEG) using a direct probe of electron-electron (e-e) scattering rates. We find evidence for an e-e scattering pr...

    Density of States and Electron-Phonon Coupling in Two-Dimensional Electron Systems at High Magnetic Fields

    One of the central problems in the two-dimensional electron field1 is the determination of the Landau level density of states. This quantity plays an essential role in determining almost all physically measurable...

    Quantum Hall Effect Experiments Using Ballistic Phonons

    The intense interest over the last few years in the quantum Hall effect[1], occuring in the 2-D electron gas (2DEG), has been sustained largely by electronic transport measurements. For example, the prediction...

    High Precision de Haas-Van Alphen Measurements on a Two-Dimensional Electron Gas

    Using a new, highly sensitive, torsional magnetometer technique, we have observed the de Haas-van Alphen Effect in GaAs/(AlGa)As two-dimensional electron systems. The measurements promise to allow direct deter...

    Atomic-beam study of the 5-min solar wavelength oscillations

    Long records of the wavelength oscillations of the solar 7699 Å potassium line have been obtained with an atomic-beam resonance-scattering apparatus taken to Kitt Peak. Data are presented giving the dependence...
