Vibration-assisted crystallization improves organic/dielectric interface in organic thin-film transistors

Abstract

Solution processability of organic semiconductors allows high-throughput fabrication on arbitrary substrates at low-cost, but the films often exhibit low performance. Here, we report on a new method for device fabrication, vibration assisted crystallization (VAC) that produces superior films, which approach the fundamental performance limits shown in corresponding single-crystal measurements.
