摘要

Organic field-effect transistors (FETs) have been fabricated by using poly(p-phenylenevinylene) (PPV) films prepared from a water soluble precursor polymer and p-channel FET conduction was obtained by using platinum source-drain electrodes. When the conversion temperatures for preparing PPV films changed between 180 and 280 degrees C, the field-effect hole mobilities changed between 4.3 x 10(-4) and 8.4 x 10(-6) cm(2) V-1 s(-1). The highest field-effect hole mobility was seen on the PPV thermally converted at 180 degrees C. The decreases in field-effect mobilities in the PPV films with further extended average p-conjugation length converted at higher temperatures were ascribed to morphological defects owing to crystallization.
