| Outline of Final Research Achievements |
This work provides a platform to study the physical properties of conjugated polymers from high carrier density to low carrier density. By varying the UV-irradiation time, the carrier density in these films is precisely controlled over more than three orders of magnitude. By measuring the Seebeck coefficient of the film as a function of the UV-irradiation time, we find a maximum power factor of ~42 microW/mK2 at a carrier density of ~5 × 1020 cm－3. Thus, the use of photoinduced dedoping not only provides a platform for understanding the physical properties of conducting polymers but also is useful for developing applications requiring patterned, large-area conducting polymers.
