Description | We have made some discoveries about the role played by electronic structure in some fundamental material properties. We have contributed to some computer software that will help in interpreting future experiments. This software is freely available. |
Exploitation Route | The research at this stage is of quite a fundamental nature. Our results relate mainly to a better understanding of exotic properties exhibited by materials. However, there is increasing use of the X-ray scattering techniques that we have ourselves used in understanding the behaviour of technologically relevant materials (e.g. batteries). The code we developed and published could be of use here. |
Sectors | Electronics Energy |
Description | Developing new technological materials can be significantly aided by having a fundamental understanding of the underlying electronic structure i.e. knowing how the electrons behave. Our research has stimulated further research in a range of areas of electronic structure and the physics of metals and alloys, including some that are quite applied in nature. |
