Piezoelectric inkjet printed films and patterns of ZnO and Mn doped ZnO: formation of bifunctional Zn0.98Mn0.02O films

Abstract

Films and patterns of ZnO and Zn_0.98Mn_0.02O semiconductors have been inkjet printed, using their precursor inks, on Si and polyimide substrates with a drop on demand inkjet printer. A Zn_0.98Mn_0.02O film printed on Si after processing showed enhanced bi-functional properties, like room temperature ferromagnetism and ultraviolet sensing, compared to diamagnetic and the ultraviolet sensing properties of a pristine ZnO film. Thus, this process opens up new possibilities of patterning advanced multifunctional materials.
