Imaging Electron Interferometer
B. J. LeRoy, A. C. Bleszynski, K. E. Aidala +6
An imaging interferometer was created in a two-dimensional electron gas by reflecting electron waves emitted from a quantum point contact (QPC) with a circular mirror. Images of el…
Thermal Electron Wavepacket Interferometry: Derivation and New Results
E. J. Heller, K. E. Aidala, B. J. LeRoy +5
A novel formal equivalence between thermal averages of coherent properties (e.g. conductance), and time averages of a single wavepacket arises for Fermi gasses and certain geometri…
Damping of micromechanical structures by paramagnetic relaxation
J. G. E. Harris, R. Knobel, K. D. Maranowski +3
We find that the damping of micromechanical cantilevers is sensitive to the relaxation dynamics of paramagnetic ions contained within the levers. We measure cantilevers containing…
Imaging Coherent Electron Flow
B. J. LeRoy, A. C. Bleszynski, M. A. Topinka +5
Images of electron flow through a two-dimensional electron gas from a quantum point contact (QPC) can be obtained at liquid He temperatures using scanning probe microscopy (SPM). A…
Superconducting Single-Electron Transistor in a Locally Tunable Electromagnetic Environment: Dissipation and Charge Fluctuations
W. Lu, K. D. Maranowski, A. J. Rimberg
We have developed a novel system consisting of a superconducting single-electron transistor (S-SET) coupled to a two-dimensional electron gas (2DEG), for which the dissipation can…
