The heating and cooling of 2D electrons at low temperatures
A. K. Jain, J. T. Nicholls, S. N. Holmes +4
We present measurements of the cooling length for hot electrons in a GaAs-based high mobility two-dimensional electron gas (2DEG). The thermal measurements are performed o…
Coulomb sensing of single ballistic electrons
J. D. Fletcher, W. Park, P. See +6
While ballistic electrons are a key tool for applications in sensing and flying qubits, sub-nanosecond propagation times and complicated interactions make control of ballistic sing…
Simultaneous study of acoustic and optic phonon scattering of electrons and holes in undoped / heterostructures
Y. Ashlea Alava, K. Kumar, C. Harsas +5
The study of phonon coupling in doped semiconductors via electrical transport measurements is challenging due to unwanted temperature-induced effects such as dopant ionisation and…
Statistical study and parallelisation of multiplexed single-electron sources
S. Norimoto, P. See, N. Schoinas +7
Increasing electric current from a single-electron source is a main challenge in an effort to establish the standard of the ampere defined by the fixed value of the elementary char…
Photon emission by hot electron injection across a lateral \textit{pn} junction
S. Norimoto, R. Saxena, P. See +5
We demonstrate a method to generate photons by injecting hot electrons into a {\it pn} junction within a \ce{GaAs/AlGaAs} heterostructure. Hot electrons are generated by biasing ac…
Fast characterization of multiplexed single-electron pumps with machine learning
N. Schoinas, Y. Rath, S. Norimoto +8
We present an efficient machine learning based automated framework for the fast tuning of single-electron pump devices into current quantization regimes. It uses a sparse measureme…
Time-of-Flight Measurements of Single-Electron Wave Packets in Quantum-Hall Edge States
M. Kataoka, N. Johnson, C. Emary +7
We report time-of-flight measurements on electrons travelling in quantum-Hall edge states. Hot-electron wave packets are emitted one per cycle into edge states formed along a deple…
Accurate high speed single-electron quantum dot preparation
S. P. Giblin, S. J. Wright, J. Fletcher +7
Using standard microfabrication techniques it is now possible to construct devices, which appear to reliably manipulate electrons one at a time. These devices have potential use as…
