Abstract

Indacenodithiophene-co-benzothiadiazole (IDTBT) belongs to a class of donor-acceptor polymers, exhibiting high electronic mobility and low energetic disorder. Applying vacuum as dielectric enables us to investigate the intrinsic charge transport properties in IDTBT. Vacuum-gap IDTBT field-effect transistors (FET) show high mobilites approaching 1 cm2V−1s−1. In addition, with increasing dielectric constant of the gate insulators, the mobilites of IDTBT transistors first increase and then decrease. The reason could be attributed to effect of both charge carrier accumulation and the presence of dipolar disorder at the semiconductor/insulator interface induced by polar insulator layer.
