Lithium niobate (LiNbO3) is used in applications such as in optoelectronics, surface acoustic wave devices and transducers. In this paper nano-patterning of LiNbO3 wafers at the wafer scale is investigated using a novel low cost and large-area nano-imprinting technique. The formation of nano-scale pillars is presented by nano-imprinting an ordered nickel etch mask by lift-off on a y-cut LiNbO3 wafer. The process lends itself to the development of novel sensors or high temperature nano-scale harvesting structures. Since one potential application for nano-pillars of piezoelectrics is energy harvesting, calculations of relevant figures of merit for LiNbO3 based composites are also presented.
