Typographical errors were inadvertently introduced into the unit of charge mobility during the production process, such that the correct unit cm2 V−1 s−1 was incorrectly give as cm−2 V−1 s−1. These errors do not affect the analysis of the results presented in the Article.

The penultimate sentence of the second paragraph of the Article should read ‘Recently, the electron mobility of n-type polymers has increased rapidly, reaching values of more than 1.0 cm2 V−1 s−1 in OFETs,12–17 thus enabling n-type OECTs operating in accumulation mode.’

Similarly, the final sentence of the fourth paragraph of the section ‘Transistor characterization’ should read ‘The electron mobilities (μe) were measured to be 1.0 × 10−4 cm2 V−1 s−1 for p(gNDI-T2) and 1.0 × 10−5 cm2 V−1 s−1 for p(gNDI-gT2).’
