The study of single-electron phenomena associated with tunnelling in semiconductor
nanostructures has emerged in recent years as a major forefront of condensed matter …

A linear-response theory is developed for resonant tunneling through a quantum dot of small
capacitance, in the regime of thermally broadened resonances. The theory extends the …

Publisher Summary Quantum transport is conveniently studied in a two-dimensional
electron gas (2DEG) because of the combination of a large Fermi wavelength and large …

The infinite-U Anderson model is applied to nonequilibrium transport through a quantum dot
containing two spin levels weakly coupled to two leads. At low temperatures, the Kondo …

We have investigated the behavior of a laterally confined quantum dot in close proximity to a
one-dimensional channel in a separate electrical circuit. When this channel is biased in the …

Nanowires, point contacts and metallic single-wall carbon nanotubes are one-dimensional
nanostructures which display important size-dependent quantum effects. Quantization due …

Narrow channels interrupted by two controlled potential barriers and having a tunable
electron density were made in GaAs, and their conductance was measured at low …

We have studied the electron transport in a one-dimensional electron interferometer. It
consists of a disk-shaped two-dimensional electron gas, to which quantum point contacts …

Transport measurements of a Coulomb island, a semiconductor dot small enough that
Coulomb interactions dominate transport are presented. At moderate magnetic fields (B= 2 …

We have studied the magnetotransport properties of an artificial one-dimensional crystal.
The crystal consists of a sequence of fifteen quantum dots, defined in the two-dimensional …
