The Semiconductor Physics group explores and develops new physics using state-of-the-art semiconductor device fabrication technology.
The particular speciality of the group is the development and study of new types of semiconductor nanostructure in which a small number of electrons, down to the single-electron limit, can be isolated and their effective dimensionality varied. This is part of the field of mesoscopic physics, or nanoelectronics, and the techniques which the group has developed have been adopted by many other groups worldwide.
In addition to this, the group applies its advanced technology to fabricate a range of novel opto-electronic structures in collaboration with a number of other leading research groups.
The group's main areas of research are:
- One-Dimensional Electron Transport
- Mesoscopic Two-Dimensional Electron Transport
- Electron Transport in Quantum Dots
- Surface Acoustic Waves (SAW)
- Quantum Light Sources and Detectors
- Low Temperature Scanning Probes
- Terahertz Science and Technology
The group has several machines used to manufacture samples for their research. These processes include:
