Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

| Description | We have developed new models for the origin of light emission from silicon nanocrystals and nanoclusters. These are important because we would like to be able to produce silicon-based light sources for integration with microelectronics. This has so far been impossible because silicon is an inefficient light emitter. The results from this project show ways in which this could be achieved. |
| Exploitation Route | Other researchers - helping them to understand the process of light emission from silicon Industry - to help develop Si-based LEDs and other light sources |
| Sectors | Aerospace, Defence and Marine,Digital/Communication/Information Technologies (including Software),Electronics,Energy |
| Description | The work on silicon-doped silicon oxide allowed us to move into a new area, studying the electrical (rather than optical) properties of this material. We have now developed a technology that exploits this in novel devices for semiconductor memories. While this is not a direct impact from this grant, it is certainly indirect. We have set up a spin-out company to commercialise this new memory technology - Intrinsic Semiconductor Technologies Ltd |
