Electron interferometer formed with a scanning probe tip and quantum point contact
M. P. Jura, M. A. Topinka, M. Grobis +3
We show an electron interferometer between a quantum point contact (QPC) and a scanning gate microscope (SGM) tip in a two-dimensional electron gas. The QPC and SGM tip act as refl…
Unexpected features of branched flow through high-mobility two-dimensional electron gases
M. P. Jura, M. A. Topinka, L. Urban +5
GaAs-based two-dimensional electron gases (2DEGs) show a wealth of remarkable electronic states, and serve as the basis for fast transistors, research on electrons in nanostructure…
Observations of Plasmarons in a System of Massive Electrons
O. E. Dial, R. C. Ashoori, L. N. Pfeiffer +1
Calculations of the single particle density of states (SPDOS) of electron liquids have long predicted that there exist two distinct charged excitations: the usual quasiparticle con…
Delocalized-localized transition in a semiconductor two-dimensional honeycomb lattice
G. De Simoni, A. Singha, M. Gibertini +7
We report the magneto-transport properties of a two-dimensional electron gas in a modulation-doped AlGaAs/GaAs heterostructure subjected to a lateral potential with honeycomb geome…
Zero differential resistance in two-dimensional electron systems at large filling factors
A. T. Hatke, H. -S. Chiang, M. A. Zudov +2
We report on a state characterized by a zero differential resistance observed in very high Landau levels of a high-mobility two-dimensional electron system. Emerging from a minimum…
Zero-Bias Anomalies in Narrow Tunnel Junctions in the Quantum Hall Regime
P. Jiang, C. -C. Chien, I. Yang +4
We report on the study of cleaved-edge-overgrown line junctions with a serendipitously created narrow opening in an otherwise thin, precise line barrier. Two sets of zero-bias anom…
