Summary on Grant Application Form
The national consortium brings together key players in the Uk to make available a wide range of techniques for fabrication and test of a range of highly innovative carbon based devices. It encompasses displays to power devices, MEM's to low cost electronics, and sensors to solar cells. the proposal covers devices made from a wide range of conjugated polymers, oligomers and organic molecules as well as the various forms of carbon: a-C, diamond, and nanotubes. The attainment of devices in materials which have high carrier mobilites and low densities of traps is the major focus of the work. As its contribution, Bangor will construct and commission an apparatus for measuring the internal photoemssion (IPE) in polymer devices based on the MIS structure. Such measurements will enable the potential barriers at electrode/insulator and electrode/semiconducting polymer interfaces will be determined. These are important parameters for the development of improved organic light light emitting diodes (OLED's). Measurements will be carried out also on materials and devices supplied by others in the network. The medium term goal of the IPE study will be the design and fabrication of a suitable insulator system for use as a non-volatile memory element compatible with plastic electronic technology. A number of commercially-available polyimides will be purchased and a material capable of of strong charge trapping will be identified and incorporated into the MIS structure. The dynamics of charge trapping and release will be examined with a view to inducing either an ON or OFF state in an MIS transistor.
