Spatially probed electron-electron scattering in a two-dimensional electron gas
M. P. Jura, M. Grobis, M. A. Topinka +3
Using scanning gate microscopy (SGM), we probe the scattering between a beam of electrons and a two-dimensional electron gas (2DEG) as a function of the beam's injection energy, an…
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…
An off-board quantum point contact as a sensitive detector of cantilever motion
M. Poggio, M. P. Jura, C. L. Degen +4
Recent advances in the fabrication of microelectromechanical systems (MEMS) and their evolution into nanoelectromechanical systems (NEMS) have allowed researchers to measure extrem…
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…
