All-brush-painted top-gate organic thin-film transistors

Abstract

Brush painting, a simple and fast solution processing technique, possesses promising multiple applications in ultra-low-cost organic electronics with large-area manufacture. Benefiting from effective brush painting of high quality conductive electrodes, semiconductive layers and dielectric layers, all-brush-painted top-gate transistors were successfully constructed with a maximum mobility of 0.14 cm² V⁻¹ s⁻¹.
