Summary on Grant Application Form |
|
The charge transport mechanism giving rise to the recently discovered high carrier mobilities in self-organised, conjugated polymer FETs, such as regioregular poly-hexylithiophene, will be investigated. The formation of polarons in these materials will be probed spectroscopically by electro-optical charge modulation spectroscopy with particular emphasis on the mid-infrared spectral range. These experiments will be performed on operational FET and LED devices and will be correleated directly with the measurement of fundamental transport coefficients such as the temperature-dependent mobility and the thermoelectric Seebeck coeffcient. The microstructure will be carefully characterised by X-ray diffraction. A broad range of self-organising materials with different types of supramolecular structure and dimentionality of the conjugated conduction paths will be compared. The improved understanding of carrier transport in these materials will provide direct, important feedback to an intense materials research programme with the goal of developing polymer FETs and charge-transporting layers in LEDs with a mobility on the order of 1 cm2/Vs.
