Tunable Antenna-Coupled Intersubband Terahertz (TACIT) Mixers: The Quantum Limit Without the Quantum Liquid
M. S. Sherwin, C. Cates, B. Serapiglia +5
At present, nearly quantum-limited heterodyne receivers for Terahertz (THz) frequencies require cooling to temperatures below 4K. We are working to build semiconductor-based "tunab…
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 wave flow in a two-dimensional electron gas
B. J. LeRoy, A. C. Bleszynski, M. A. Topinka +5
We measure the energy distribution of electrons passing through a two-dimensional electron gas using a scanning probe microscope. We present direct spatial images of coherent elect…
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…
