Directly drawn organic transistors by capillary pen: a new facile patterning method using capillary action for soluble organic materials

Abstract

A capillary pen drawing technique, developed as a new patterning methodology for the large-area patterning and fabrication of organic electronics, provides several advantages over conventional approaches: the method is simple and versatile, there are no restrictions on the patterning shapes that could be produced, and the method can be tailored to a variety of substrates.
