AI Article Synopsis
- Researchers developed organic field-effect transistors using hydrogen-bonded diketopyrrolopyrrole-thiophene co-oligomers made through a solution-process method.
- The devices were annealed at 200 °C, which helped improve their performance.
- They demonstrated ambipolar charge-carrier transfer, achieving field-effect mobilities of μ(h) = 6.7 × 10(-3) cm(2) V(-1)s(-1) for holes and μ(e) = 5.6 × 10(-3) cm(2) V(-1)s(-1) for electrons.
Article Abstract
Organic field-effect transistors with hydrogen-bonded diketopyrrolopyrrole-thiophene co-oligomers were fabricated by a solution-process method with annealing at 200 °C, showing ambipolar charge-carrier transfer with field-effect mobilities up to μ(h) = 6.7 × 10(-3) cm(2) V(-1)s(-1) and μ(e) = 5.6 × 10(-3) cm(2) V(-1) s(-1).
