Development of SiC optical ring resonators with Zinc Oxide nanowire detection for monitoring ammonia in the environment

The project aims to address a need for the Centre of Ecology and Hydrology who monitor Ammonia in the environment, especially in areas of concern such as pig farms where the high ammonia content can affect the environment.

Currently sensors of sufficient sensitivity for environmental monitoring of ammonia are not readily available for continuous readout, instead samples are collected monthly and analysed in a laboratory with no record of distribution timeline. This project will combine a previously investigated zinc nanowire detection mechanism with an optical ring resonator aiming to give continuous data at the required sensitivity enabling accurate chemical/environmental monitoring.

The successful applicant will initially work with Heriot Watt to model the device and produce a design before learning fabrication techniques in Edinburgh University cleanroom and fabricating devices. Working with the Centre of Ecology and Hydrology to expose the samplesand the performance would then be characterised at the Optics facilities at Heriot Watt.
