Reduction of the Error in the Electrical Characterization of Organic Field-Effect Transistors Based on Donor–Acceptor Polymer Semiconductors

Abstract

In terms of their electrical characteristics, organic field-effect transistors (OFETs) based on donor-acceptor (D-A) polymer semiconductors show a significant dependence on the materials used and measurement conditions. In this study, a variety of measurement methods for OFETs based on D-A polymer semiconductors are presented to reveal errors in electrical characterization including field-effect mobility and threshold voltage. By systematically evaluating the electrical characteristics under various measurement conditions, we can obtain adequate electrical parameters, providing accurate values for circuit designers and avoiding overestimation. © 2022 ACS Applied Electronic Material.
