Predictive Model for the Meniscus‐Guided Coating of High‐Quality Organic Single‐Crystalline Thin Films

Abstract

A model that describes solvent evaporation dynamics in meniscus-guided coating techniques is developed. In combination with a single fitting parameter, it is shown that this formula can accurately predict a processing window for various coating conditions. Organic thin-film transistors (OTFTs), fabricated by a zone-casting setup, indeed show the best performance at the predicted coating speeds with mobilities reaching 7 cm2 V−1 s−1.
