TL;DR: In this article, the authors present experimental results and a supporting theory, showing that a one-dimensional system in which transport is ballistic possesses a quantised resistance, h/2ie2, where i is the number of occupied 1D sub-bands and the spin degeneracy is two.

TL;DR: The behavior of a laterally confined quantum dot in close proximity to a one-dimensional channel in a separate electrical circuit is investigated, finding the activation energy of transport through the dot is much lower than expected.

TL;DR: In this article, the authors present a different pumping mechanism of single charges, whereby electrons "surf" as particles on a time-dependent potential instead of tunnelling through the barriers as waves.

TL;DR: Here it is shown how a single electron may be captured in a surface acoustic wave minimum and transferred from one quantum dot to a second, unoccupied, dot along a long, empty channel.

TL;DR: An experimental investigation of the direct current induced by transmitting a surface acoustic wave (SAW) through a quasi-one-dimensional (1D) channel defined in a GaAs - AlGaAs heterostructure by a split gate finds that at low SAW power levels the current reveals oscillatory behaviour as a function of the gate voltage with maxima between the plateaux of quantized 1D conductance.
