Abstract

Silver (Ag) seeds for assisting femtosecond laser direct writing (FsLDW) were employed in the fabrication of microelectrodes (MEs). Pattern-controllable and size-tunable MEs can be easily constructed by introducing Ag seeds to the ion precursor solution in the process of laser-induced photoreduction of the Ag ions. The fabrication process is stable under sufficient material supply, and the applied laser power is reduced to one-tenth of that without Ag seeds. Finally, as a representative application, an organic field effect transistor (OFET) was fabricated, based on this laser-fabricated Ag ME. The OFET exhibited good photoelectric properties, and achieved an on–off ratio of 200.
