Direct Laser Writing of Complementary Logic Gates and Lateral p–n Diodes in a Solution‐Processible Monolithic Organic Semiconductor

Abstract

Complementary organic logic circuits and lateral bipolar microstructures with specified p- and n-region profiles can be patterned by direct laser writing in solution- processed thin films faricated from a quinoidal oligothiophene derivative. To demonstrate the versatility of this method, the fabrication of NAND and NOR logic gates as well as a gate-modulated lateral p-n diode is reported (see figure).
