Abstract

Organic electrochemical transistors (OECTs) are promising for biosensing, but their CMOS integration is limited by insufficient understanding of geometry-dependent transport. Here, we show that OECT behavior deviates from simple scaling due to non-uniform electrochemical doping. Using physics-based finite element modeling calibrated with experiments, we analyze short-channel planar and vertical accumulation-mode OECTs. Device architecture controls electric-field distribution and active channel volume, leading to deviations from the Bernards–Malliaras model. These results establish design rules for CMOS-compatible OECTs.
