Summary on Grant Application Form
The Cambridge group wishes to build on the existing collaboration in polymer LEDs to realise the design of high quality semiconducting polymers with achievement of the required uniaxial orientation for application in FETs. Design principles will focus on polymer purity, regioregular coupling protocols, use of liquid crystallinity and self assembly to achieve inter and intrachain order. The scope of this project is to raise field-effect carrier mobilities through improvements in the structural order in the materials used. This requires both chemical synthesis of new polymers which can show improved self-organisation, and a range of fabrication techniques and characterisations of electrical and electro-optical properties. Besides the direct focus on device performance, the range of measurements of devices will allow very direct measurements of fundamental aspects of the electronic excitations in these materials, with a particular emphasis on understanding the role of disorder in the stabilisation of the different excited states (polarons, bipolarons, ....... dimers).
