In this review a survey of tunnelling processes between barrier-separated two-dimensional
(2D) systems and systems of different dimensionality is given. Tunnelling between barrier …

Tunneling processes between subbands in two independently contacted two-dimensional
electron-gas systems on a GaAs-Al x Ga 1− x As-GaAs heterostructure were investigated …

We derive the dispersion relation for magnetoplasmons in the random-phase approximation
for a quantum-wire superlattice in the limit of strong lateral modulation and with a quantizing …

We have resolved the bound states of a one-dimensional quantum wire by resonant electron
tunneling. The atomically precise quantum-confined structure was prepared by cleaved …

A numerical method is developed to determine the subband energies and electron
concentrations in shallow etched quantum wires from magnetotransport data. Solving the …

By applying a shallow etching technique, the electrons in a remote doped GaAs/AlGaAs
quantum well and the photogenerated holes are separated into adjacent lateral regions. The …

We have stuied the tunneling processes between a multiple-quantum-wire system and a two-
dimensional electron gas. In magnetic fields applied perpendicular to the sample, transitions …

An atomically precise double asymmetric quantum-wire structure was fabricated with the
cleaved edge overgrowth method. A resonant tunneling diode for such a structure was …

We report on recent investigations of electron transport characteristics in the transition
regime from a two-dimensional (2DEG) to a one-dimensional electron gas (1DEG). Electron …

Incorporating the spin-orbit interaction into the Hamiltonian of a quantum wire, we have
calculated the plasma excitation energies. We include both the Rashba term (α coupling) …
