ORGANIC THIN FILM TRANSISTORS AND METHODS OF MAKING THE SAME

摘要

In one aspect, organic thin film transistors are described herein. In some embodiments, an organic thin film transistor comprises a source terminal, a drain terminal and a gate terminal; a dielectric layer positioned between the gate terminal and the source and drain terminals; and a vibrationally-assisted drop-cast organic film comprising small molecule semiconductor in electrical communication with the source terminal and drain terminal, wherein the transistor has a carrier mobility (μeff) of at least about 1 cm2/V·s.
