Hybrid inorganic-organic micro-devices combining gallium nitride and polymers

This thesis presents a study on the integration of polymer organic materials, onto GaN-based micron-scale light-emitting diodes, or 'micro-LEDs'. Several pertinent micro-patterning techniques are investigated along with their used in the realisation of such hybrid devices. Polymers are an attractive family of materials whose properties can be tailored to the requirements of specific applications. The interest of this thesis focuses on an 'in-house' synthesised transparent polymer ('HTP2') designed for encapsulation of micro-LEDs emitting in the UV-blue region of the spectrum and on conjugated light-emitting materials whose semiconducting properties are used in this work for colour conversion.
