Project: Performance of Organic Materials for Mobile Electronics

The aim of this project is to develop and characterise a new class of low band-gap, high mobility organic semiconductors and associated dielectrics for use in high value consumer electronics products. Current generations of organic semiconductors which are used industrially often have good processing characteristics (e.g. good uniformity, good environmental stability, appropriate solubility), but are limited in their mobility which in turn limits the application spaces where they can be used. Other materials have been shown to yield higher mobility, but exhibit poorer uniformity and yield characteristics. Materials that combine a high mobility with the processing characteristics required for high-volume manufacturing would be of immense value to the organic electronics industry, opening up a range of application spaces, not only in the field of displays but also logic and photovoltaic devices. The first objective is to produce materials which can demonstrate amorphous silicon like behaviour (mobility > 1 cm2/Vs) in a large-area thin film transistor (TFT) array structure with a high level of uniformity and operational reliability. This technology will also need to meet all other commercial performance, volume and cost requirements. The second objective is to produce e-reader displays using these materials and fully characterise their performance against the consumer requirements and lifetime expectations for such displays. The final objective is to characterise the materials in order to better understand in-depth charge transport, charge injection, and other performance aspects in terms of the basic molecular and electronic structure.If successful, the project will accelerate the application of organic electronics in a broad range of consumer electronics applications such as next generation e-readers and other display technologies, such as OLED, as well as logic circuit applications and photovoltaics. It will also lead to improved scientific understanding of the requirements for achieving high charge carrier mobilities in solution-processed, low band-gap organic semiconductors.
