Hot paper: Fabrication of ZnO nanodisc arrays using nanoimprint lithography

Fabrication of ZnO nanodisc arrays is reported using nanoimprint lithography (NIL) mold obtained sub-100 nm pattern resolution by Srinivasan, Krishnamoorthy and co-workers.

ZnO nanostructures have many applications such as use in LEDs, gas sensors and semiconducting devices. Controlling the densities, geometric attributes and batch to batch reproducibility of nanostructured ZnO can be a challenge. In this hot paper, a generic process is described, using block copolymer assisted NIL, to produce high-resolution NIL molds for the production of ZnO nanodiscs. The authors also investigate the charge storage properties of the produced ZnO nanodiscs.
