Balanced Ambipolar OECTs through Tunability of Blend Microstructure.

ABSTRACT: Organic electrochemical transistors (OECTs) are promising building blocks for bioelectronics, bridging ionic biological signals and electronic circuits. Ambipolar OECTs, capable of both n- and p-type charge transport, are highly desirable for versatile bioelectronic applications, offering a simplified circuit design and enhanced sensing capabilities. However, achieving a balanced ambipolar performance remains a materials science challenge. Here we show that blending judiciously selected unipolar p-type and n-type organic mixed ionic-electronic conductors (OMIECs), and most importantly, tuning film microstructure through composition and thermal treatment, can be leveraged to attain balanced ambipolar OECTs with near-equal n-type and p-type performances, both in the transconductance and in s
