This project intends to create new light-emitting display technology with the potential to offer much cheaper, recyclable, and mechanically flexible semiconductors. Organic light-emitting field effect transistors are an emerging class of integrated optoelectronic device with dual functionalities (ie a light emitting and a switch transistor in single device structure). The dual-functioned devices provide a promising pathway to much more economical display technologies and tunable organic lasers. The principal goal of this project is to develop a new route to achieve simplified display pixels and electrically pumped organic lasers by using organic light-emitting transistors platform with new organic chromophores. The new semiconductors could be easily integrated into a wide range of applications such as telecommunications, biomedical and consumer electronics.Read moreRead less
Silicon-germanium-carbon - a novel opto-mechanic material for optical micro-electromechanical systems. Evolving from past black-and-white images, through present red-green-blue multi-spectral capability, future remote imaging systems promise spectroscopic functionality across much broader wavelength ranges in a low-cost system. However, the high cost of multiple materials and technologies for each specific spectral band limits them to high-cost industry sectors.

Evolving from past black-and-white images, through present red-green-blue multi-spectral capability, future remote imaging systems promise spectroscopic functionality across much broader wavelength ranges in a low-cost system. However, the high cost of multiple materials and technologies for each specific spectral band limits them to high-cost industry sectors. This project proposes a simple, low-cost, single material technology based on silicon-germanium-carbon thin films for mechanical and optical applications from ultraviolet to long-wave infrared, enabling widespread application of spectroscopic imaging to multiple fields extending from climate change research, through resource exploration, to cancer detection, and aerospace/defense.Read moreRead less
Towards energy-efficient lighting based on light-emitting diodes: the role of silicon carbide grown on Si Wafers. This project will investigate a potential solution to the problems of cost and quality of light-emitting diodes for solid-state lighting. The expected outcome is knowledge to underpin future development of solid-state lighting that is suitable for a wide replacement of the much less efficient and effective incandescent bulbs and fluorescent tubes.
