The main drive for our activities is to bridge a gap between the nano-world and real life applications. In particular, solution processable semiconducting nano-blocks, including inorganic nanowires, conjugated polymers and carbon nanotubes can be deposited by wet-coating methods and various self-assembly techniques to result in large area electronics.
Solution-based fabrication of electronic and opto-electronic devices using functional ‘inks’ at low temperatures and on large area substrates is an attractive printed electronics technology for the development of low-cost, lightweight and flexible electronics, including:
- Memory elements
- Energy harvesting and storage devices
- Reconfigurable antennas.
We utilise a variety of printing techniques for materials deposition including ink-jet printing, screen printing, slot-die coating, wire bar coater to produce the most important electronics ‘building blocks’ such as field-effect transistors, diodes, photovoltaic cells, photoconducting elements, photodiodes and sensors. Fabrication of conducting tracks is essential for all types of devices.
The ability to produce customisable, digitally printable, antennas and reflectors for RF applications with integrated printable switching elements has opened vast opportunities for low-cost fabrication of microwave devices.
