In this review, we discuss the results of recent experimental studies of the low-temperature
electron dephasing time (τ ϕ) in metal and semiconductor mesoscopic structures. A major …

The integer quantised conductance of one-dimensional electron systems is a well-
understood effect of quantum confinement. A number of fractionally quantised plateaus are …

We review recent theoretical work on thermoelectric energy harvesting in multi-terminal
quantum-dot setups. We first discuss several examples of nanoscale heat engines based on …

In this introductory chapter several basic concepts, relevant for mesoscopic electron
transport, will be described. The aim is to provide a basis for several of the following …

Whenever a physicist visits the physics faculty in Dortmund, he/she is bound to hear the
success story of the so-called integrated course, a four-semester introduction to physics …

Besides the usual conductance plateaus at multiples of 2 e 2/h, quantum point contacts
typically show an extra plateau at∼ 0.7 (2 e 2/h), believed to arise from electron-electron …

The controlled growth of nanowires (NWs) with dimensions comparable to the Fermi
wavelengths of the charge carriers allows fundamental investigations of quantum …

Silicon has many attractive properties for quantum computing, and the quantum-dot
architecture is appealing because of its controllability and scalability. However, the multiple …

We observe a small but definite decrease in quantized conductance at low temperatures in 2
to 10 μm-long single-mode quantum wires. The temperature dependence is stronger in the …

We have investigated the transport properties of one-dimensional (1D) constrictions defined
by split-gates in high quality G a A s/A lx Ga 1− x As heterostructures. In addition to the usual …
