Time-resolved Coulomb collision of single electrons
J. D. Fletcher, W. Park, S. Ryu +7
Precise control over interactions between ballistic electrons will enable us to exploit Coulomb interactions in novel ways, to develop high-speed sensing, to reach a non-linear reg…
Decoupling of the many-body effects from the electron mass in GaAs by means of reduced dimensionality
P. M. T. Vianez, Y. Jin, W. K. Tan +6
Determining the (bare) electron mass in crystals is often hindered by many-body effects since Fermi-liquid physics renormalises the band mass, making the observed effective m…
Engineering electron wavefunctions in asymmetrically confined quasi one-dimensional structures
S. Kumar, M. Pepper, H. Montagu +4
We present results on electron transport in quasi-one dimensional (1D) quantum wires in GaAs/AlGaAs heterostructures obtained using an asymmetric confinement potential. The variati…
Microscopic metallic air-bridge arrays for connecting quantum devices
Y. Jin, M. Moreno, P. M. T. Vianez +5
We present a single-exposure fabrication technique for a very large array of microscopic air-bridges using a tri-layer resist process with electron-beam lithography. The technique…
Observing separate spin and charge Fermi seas in a strongly correlated one-dimensional conductor
P. M. T. Vianez, Y. Jin, M. Moreno +9
An electron is usually considered to have only one form of kinetic energy, but could it have more, for its spin and charge, by exciting other electrons? In one dimension (1D), the…
Demonstration of electron focusing using electronic lenses in low-dimensional system
Chengyu Yan, Michael Pepper, Patrick See +3
We report an all-electric integrable electron focusing lens in n-type GaAs. It is shown that a pronounced focusing peak takes place when the focal point aligns with an on-chip dete…
