Areas of Focus:

• Polymer Electronics
• Organic Lasers
• Contact Formation
• Nanolithography
• Molecular wire and diodes

The intense organic electronics research activity of the last decade in beginning to come to fruition with new products entering the marketplace, with more in the pipeline. The key materials in this research field, small organic molecules and polymers, are electrically and optically active leading to a range of applications in displays, circuits and tunable lasers. Despite this success, significant effort is still required to optimise the devices in these products.

Research in this CAFMaD stream is directed towards understanding the nature of interfaces e.g. insulator-semiconductor and contact-semiconductor interfaces, which are a source of device instability and degradation in organic MISFETs and OLEDs. Significant effort is also being devoted to next generation devices where nanolithography and self-assembly techniques are being exploited to fabricate and characterise single molecule rectifiers.
