22_15b/2010Direct Laser Writing: Direct Laser Writing of Complementary Logic Gates and Lateral p–n Diodes in a Solution-Processible Monolithic Organic Semiconductor (Adv. Mater. 15/2010)

Jean-Charles Ribierre and co-workers report on the conversion of the majority carrier type by laser irradiation in solution-processed organic thin films based on a quinoidal oligothiophene derivative (p. 1722). Patterning of p-type and n-type microstructures is achieved by direct laser writing and can be visualized using a Kelvin-probe force microscope. The method is extremely promising for the fabrication of CMOS logic circuits and lateral p-n diodes based on a monolithic solution-processible organic semiconductor.
