To achieve these aims the group has developed a range of sophisticated technologies for the fabrication of devices of the highest quality, much of the group’s research relying on the technique of molecular beam epitaxy (MBE). Recent work has seen the start of a number of projects based on carbon electronics. These rely on using either graphene, a single layer of carbon atoms with very unusual properties, or carbon nanotubes, a single layer of carbon atoms rolled up into a tube structure.
The group also works in collaboration with a number of other researchers at the Cavendish, Material Science and Engineering as well as with many other universities and industrial research laboratories such as Toshiba, TeraView and the National Physical Laboratory (NPL).
Examples of the research undertaken in the group are:
Single and entangled photon sources
Coupled electron-hole gases
Quantum computing using surface acoustic waves
Gate defined quantum dots
The group has several machines used to manufacture samples for their research. These processes include:
