Objective

This objective will be achieved by the use of preferably self-organising precursor polymers. Application will enhance the intra chain (pi-pi)overlap and, hence will increase the field-effect mobility. Precursors will be based on polythiophene and polythienylenevinylene. Order will be induced by using orienting layers and by using precursors with mesogenic end groups. The degree of order will be varied by varying the chain length in a series of well-defined oligomers to the corresponding polymer. The relation between microstructural order and field-effect mobility will be established. The new materials will be tested in discrete MISFETs. Compact models describing electrical transport will be derived, and used for construction of logic gates that will display voltage amplification. As demonstrators these gates will then be integrated into simple electronic circuits which show the ability to perform logic operations, such as ring oscillators. The final result will be new materials designed for plastic logic, viz. simple polymeric electronic circuits.

In the microelectronics industry there exists a need for a new semiconductor technology to be applied in those areas where standard IC technology based on single crystalline silicon is either not feasible or too powerful and expensive. This holds for low-end high-volume applications as contactless radio frequent identification tags. Here, a low cost technology is envisaged based on semi-conducting polymers as the active element in microelectronic devices.

This basic research project is the onset in achieving the above mentioned goal. Its objective will be development and microstructural optimisation of new precursor polymers in metal-insulator-semiconductor field-effect transistors (MISFETs). The operating frequency of the MISFETs devices, now demonstrated to be 500 Hz, will be improved to 50 kHz, the lower limit for contactless RF identification tags.
