Project outcomes
Low cost, portable sensors are becoming commonplace for example in mobile phones that monitor temperature, pressure and humidity. A new generation of sensors is urgently required that can rapidly test for diseases such as bacterial infections, monitor glucose or pollutant gases.

The community was formed from four internationally renowned optoelectronics research groups at Bath, Bristol, Cardiff and Exeter. The University of Bath’s world leading Gallium Nitride (GaN) nanorod technology was distributed amongst all partners. Characterisation, modelling and device design was initiated. This developed a detailed understanding of the potential of GaN nanorod technology for use in nanoscale sensors including fabrication approaches for optical waveguides.

We are developing applications for ESPRC grants on GaN-Graphene integrated structures and GaN nanorod based sensors. A number of journal and conference papers have been produced. We have presented two papers at a major US conference in New York.
