Optimized Charge Transport in Molecular Semiconductors by Control of Fluid Dynamics and Crystallization in Meniscus‐Guided Coating (Adv. Funct. Mater. 2/2022)

Abstract

Optimized Charge Transport In article number 2107976, Jasper J. Michels, Wojciech Pisula, Tomasz Marszalek, and co-workers identify an optimal processing window for zone-casting of a molecular semiconductor for organic fieldeffect transistors. Computational modelling of the fluid dynamics and the crystallization explains the occurrence of three morphological subregimes: i) isotropic domain-like, ii) unidirectional crystal stripes and iii) corrugated dendritic. Control of the semiconductor film morphology allows to optimize the in-plane charge carrier transport.
