F1-A (maj 27 2002), E1-A (dec 10 2001) |
| Recommended semester: 4th -7th semester |
| Scope and form: Lectures, tutorials and small projects. |
| Evaluation: Oral exam and approval of reports
|
| Examination: 13-scale |
| Previous course: 10227 / 10421 / 44202 |
| Prerequisites: 10110 / 10201, 10203 / 10300, 10013 / 10015 / 48000 / 10100 / 10207 / 33253 / 31400 |
| Aim: To give the student a basic understanding of modern electronic quantum devices based on e.g. superconductivity, quantum mechanical tunneling and charge transport in one- and two-dimensional nano systems. |
Contents: A number of quantum-electronic devices will be introduced and discussed. An introduction to small scale superconductivity is given: Flux quantisation, the Josephson effect, quantum interference, high frequency components and detectors, transition edge detectors, the voltage standard, Josephson oscillators, digital circuits and components based on single flux quanta. Another topic is charge transport in spatially restricted structures: Ballistic transport, the simple two-dimensional electron gas, conduction in narrow channels, the Landauer-Buttiker model, the quantum Hall effect, localisation, resistance fluctuations, and carbon nanotubes. A third topic is hybrid components: Interfaces between e.g. ferromagnets and metals, or superconductors and semiconductors. Finally, an introduction is given to single electron and Cooper pair tunneling in nanometer junctions: Coulomb blockade, single electron transistor, electron pump, current standard, and Coulomb blockade thermometer. The noise properties are discussed in each case.
