Abstract Scope |
Zinc Oxide (ZnO) is a well-regarded ceramic material in use for over 150 years as a pigment in paint and cosmetics. In the 1950s, ZnO was found to exhibit a high piezoelectric coefficient among other favorable optoelectronic properties (wide bandgap semiconducting behavior, optical transparency, and photoluminescence) and has since been used as a piezoelectric element in conventional electronics. The rise of additive manufacturing and printed electronics has renewed interest in ZnO as a versatile feed material for piezoelectric and optoelectronic devices. Within this study, the state of ZnO printing is reviewed, a methodology for deposition/post-processing of ZnO films is developed, and the general feasibility of in situ reactive inkjet printing of ZnO is explored.
